FIELD OF THE INVENTION
This invention relates to foamable thermoplastic compositions, thermoplastic foams, foaming methods, and systems and articles made from same.
BACKGROUND
While foams are used in a wide variety of applications, developing a foam that has excellent performance properties and is cost-effective to produce is a derisible but difficult goal to achieve. It is even more difficult to achieve this goal while at the same time developing a foam that is environmentally friendly. Producing environmentally friendly foams is especially difficult because they comprise both a blowing agent component and a resin component forming the foam structure, and each of these components has an impact on foam performance and on environmental properties. Environmental considerations include not only the recyclability and sustainability of the polymeric resin that forms the structure of the foam but also the low environmental impact of blowing agents used to form the foam, such as the Global Warming Potential (GWP) and Ozone Depletion Potential (ODP) of the blowing agent. It is therefore a major challenge to develop a foam that simultaneously has excellent performance and can be produced cost-effectively from an environmentally friend blowing agent and an environmentally friendly resin.

FIELD OF THE INVENTION
This invention relates to foamable thermoplastic compositions, thermoplastic foams, foaming methods, and systems and articles made from same.
BACKGROUND
While foams are used in a wide variety of applications, developing a foam that has excellent performance properties and is cost-effective to produce is a derisible but difficult goal to achieve. It is even more difficult to achieve this goal while at the same time developing a foam that is environmentally friendly. Producing environmentally friendly foams is especially difficult because they comprise both a blowing agent component and a resin component forming the foam structure, and each of these components has an impact on foam performance and on environmental properties. Environmental considerations include not only the recyclability and sustainability of the polymeric resin that forms the structure of the foam but also the low environmental impact of blowing agents used to form the foam, such as the Global Warming Potential (GWP) and Ozone Depletion Potential (ODP) of the blowing agent. It is therefore a major challenge to develop a foam that simultaneously has excellent performance and can be produced cost-effectively from an environmentally friend blowing agent and an environmentally friendly resin.
Foams based on certain thermoplastic resins, including polyester resins, have been investigated for potential advantage from the perspective of being recyclable and/or sustainably-sourced. However, difficulties have been encountered in connection with the development of such materials. For example, it has been a challenge to develop polyester resins that are truly recyclable, can be produced from sustainable sources, and which are compatible with blowing agents that are able, in combination with the thermoplastic, to produce foams with good performance properties. In many applications the performance properties that are considered highly desirable include the production of high-quality closed cell foams that are low density (and therefore have a low weight in use) and, at the same time, have relatively high mechanical integrity and strength.

While the use of polyester materials to make foams that have essentially no closed cells, as required by EP '836, may be beneficial for some applications, a disadvantage of such structures is that, in general, open cell foams will exhibit relatively poor mechanical strength properties.
While plastics based on 2,5-furandicarboxylic-acid-based polyester have been noted to have some potential advantages in certain applications, such as having good gas barrier properties, there has also been a recognition of substantial problems with forming foam materials from such plastic materials. For example, CN108410000 teaches that
2,5-furandicarboxylic-acid-based polyesters have foaming performance that is very poor and processing conditions that are extremely unfavorable. These problems are said to be addressed by using a glassy (i.e., amorphous) polymer sheet and then exposing the sheet to a special, relatively complex and cumbersome dual blowing agent process.
The process described in CN108410000 suffers from several disadvantages, including requiring an undesirably long processing time to produce the specialized, treated preform and the use of a relatively complicated dual blowing agent process. This process is also highly disadvantageous in that it is not readily adaptable for use in connection with currently used commercial extrusion equipment, thus having an undesirably high new capital cost requirement to implement.
CN 108484959 also recognizes that 2,5-furandicarboxylic-acid-based polyesters (such as PEF) have poor foamability and attempts to address this significant problem by forming a high melt viscosity polymer by blend-reacting 2,5-furandicarboxylic acid ethylene glycol ester with a multifunctional monomer selected from alcohols, esters, alkanes, carboxylic acids and CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) anhydrides. Foaming properties of this material are said to be improved relative to PEF, but no information on the foaming process is provided.
US 2020/0308363 and US 2020/0308396 each disclose the production of amorphous polyester copolymers that comprise starting with a recycled polyester, of which only PET is exemplified, as the main component and then proceeding through a series of processing steps to achieve an amorphous co-polymer, that is, as copolymer having no crystallinity. These publications indicate that it is not possible to readily form low density polyester foams from crystalline or semi-crystalline polymers and indicates that this problem can be solved by forming amorphous copolyester polymer material and using such amorphous material to form the foam.
The synthesis of poly(ethylene furanoate) (PEE) using ethylene glycol and 2,5-furandicarboxylic acid is mentioned but is not exemplified. Essentially amorphous (i.e., no crystallinity as per 0 J/G AH before foaming) ternary copolymers formed from PET, polytrimethylene furanoate and polycarbonate are said to have been foamed using CO2 as the blowing agent. No foam properties are disclosed. A wide variety of different classes of blowing agent are mentioned for use with amorphous polymers generally, including CO2, HF0-1233zd, cyclopentane, acetone and methanol.
US 9790342 discloses foams formed from the polyphenolic tannin, which may be combined with a large number of possible monomers, and among the list of monomers is 2,5-furandicarboxylic acid. The foams are said to be partially open cell and partially closed cell, with open cell content being less than 50%. Numerous potential blowing agents are disclosed, including the halogenated olefin HF0-1336mmz.
With respect to blowing agents, the use generally of halogenated olefin blowing agents, including hydrofluoroolefins (HF0s) and hydrochlorofluorolefins (HCF0s), for several specific thermoplastic foams is known, as disclosed for example in US 2009/0305876, which is assigned to the assignee of the present invention, and which is incorporated herein by reference. While the '876 application discloses the use of HFO and HFCO blowing agents with various thermoplastic materials to form foams, including PET, there is no disclosure or suggestion to use any of such blowing agents with any other type of polyester resin.
Applicants have overcome the problem of forming a high performance foam that is also has favorable environmental features (i.e., high sustainability and low atmospheric impact) and in so doing have come to appreciate that these problems can be overcome and that one or more unexpected advantages can be achieved by the formation of thermoplastic foams, and in particular extruded thermoplastic foams, using a polyester resin as disclosed herein in combination with a blowing agent comprising one of more hydrohaloolefin as disclosed herein.

For those embodiments of the present invention involving PEF copolymers, it is contemplated that those skilled in the art will be able, in view of the teachings contained herein, to select the type and amount of co-polymeric materials to be used CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) within each of the ranges described herein to achieve the desired enhancement/modification of the polymer without undue experimentation.
For those embodiments of the present invention involving the use of PEF
homopolymer or PEF copolymer, it is contemplated that such material may be formed with a wide variety of molecular weights and physical properties within the scope of the present invention. In preferred embodiments, the foams, including each of Foams 1 ¨
6, are formed from PEF having the ranges of characteristics identified in Table 1 below, which are measured as described in the Examples hereof:
Broad Range Intermediate Narrow Range Range Polymer property Molecular weight 25,000¨ 150,000 45,000¨ 130,000 55,000¨

Crystallinity, % 25 - 75 30 ¨ 60 40 ¨ 50 In general, it is contemplated that those skilled in the art will be able to formulate PEF polymers within the range of properties described above without undue experimentation in view of the teachings contained herein. In preferred embodiments, however, PEF in general and PEF
homopolymer in particular having these properties is achieved using one or more of the synthesis methods described above, in combination with a variety of known supplemental processing techniques, including by treatment with chain extenders, such as PMDA, and/or SSP
processing. It is believed that, in view of the disclosures contained herein, including the polymer synthesis described in the Examples below, a person skilled in the art will be able to produce PEF polymers within the range of characteristics described in the table above and elsewhere herein.
An example of the process for chain extension treatment of polyesters is provided in the article "Recycled poly(ethylene terephthalate) chain extension by a reactive extrusion process,"

As explained in US 1009/0264545, which is incorporated herein by reference, chain extenders generally are typically compounds that are at least di-functional with respect to reactive groups which can CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) react with end groups or functional groups in the polyester to extend the length of the polymer chains. In certain cases, as disclosed herein, such a treatment can advantageously increases the average molecular weight of the polyester to improve its melt strength and/or other important properties. The degree of chain extension achieved is related, at least in part, to the structure and functionalities of the compounds used. Various compounds are useful as chain extenders. Non-limiting examples of chain extenders include trimellitic anhydride, pyromellitic dianhydride (PMDA), trimellitic acid, haloformyl derivatives thereof, or compounds containing multi-functional epoxy (e.g., glycidyl), or oxazoline functional groups.
Nanocomposite material such as finely dispersed nanoclay may optionally be used for controlling viscosity.
Commercial chain extenders include CESA-Extend from Clariant, Joncryl from BASF, or Lotader from Arkema. The amount of chain extender can vary depending on the type and molecular weight of the polyester components. The amount of chain extender used to treat the polymer can vary widely, and in preferred embodiments ranges from about 0.1 to about 5 wt. %, or preferably from about 0.1 to about 1.5 wt. %. Examples of chain extenders are also described in U.S. Pat. No. 4,219,527, which is incorporated herein by reference.
An example of the process for SSP processing of poly(ethylene furanoate) is provided in the article "Solid-State Polymerization of Poly(ethylene furanoate) Biobased Polyester, I: Effect of Catalyst Type on Molecular Weight Increase,' Nejib Kasmi, Mustapha Majdoub, George Z.

For clarity, it will be noted that definition of the foams in the Table below all begin with only the letter F, in contrast to the foams defined by the paragraphs in the summary above, which begin with the capitalized word Foam.
In general, the forming step involves first introducing into a PEF polymer of the present invention, including each of TPP1 ¨ TPP6, a blowing agent of the present invention, including each of Blowing Agents 1 ¨ 31, to form a foamable PEF
composition comprising PEF and blowing agent. One example of a preferred method for forming a foamable PEF composition of the present invention is to plasticize the PEF, preferably comprising heating the PEF to its melt temperature, preferably above its melt temperature, and thereafter exposing the PEF melt to the blowing agent under conditions effective to incorporate (preferably by solubilizing) the desired amount of blowing agent into the polymer melt.
In preferred embodiments, the foaming methods of the present invention comprise providing a foamable composition of the present invention, including each of FC1 ¨ FC8 and foaming the provided foamable composition. In preferred embodiments, the foaming methods of the present invention comprising providing a foamable composition of the present invention, including each of FC1 ¨ FC8, and extruding the provided foamable composition to form a foam of the present invention, including each of Foams 1 ¨ 6 and each of foams Fl ¨ F8.
Foaming processes of the present invention can include batch, semi-batch, continuous processes, and combinations of two or more of these. Batch processes generally involve preparation of at least one portion of the foamable polymer composition, including each of FC1 ¨ FC8, in a storable state and then using that portion of foamable polymer composition at some future point in time to prepare a foam.
Semi-batch process involves preparing at least a portion of a foamable polymer CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) composition, including each of FC1 ¨ FC8, and intermittently expanding that foamable polymer composition into a foam including each of Foams 1 ¨6 and each of foams Fl ¨
F8, all in a single process. For example, U.S. Pat. No. 4,323,528, herein incorporated by reference, discloses a process for making thermoplastic foams via an accumulating extrusion process. The present invention thus includes processes that comprises: 1) mixing PEF thermoplastic polymer, including each of TPP1 ¨ TP P6, and a blowing agent of the present invention, including each of Blowing Agents 1 ¨ 31, under conditions to form a foamable PEF composition; 2) extruding the foamable PEF
composition, including each of FC1 ¨ FC8, into a holding zone maintained at a temperature and pressure which does not allow the foamable composition to foam, where the holding zone preferably comprises a die defining an orifice opening into a zone of lower pressure at which the foamable polymer composition, including each of FC1 ¨ FC8, foams and an openable gate closing the die orifice; 3) periodically opening the gate while substantially concurrently applying mechanical pressure by means of a movable ram on the foamable polymer composition, including each of FC1 ¨ FC8, to eject it from the holding zone through the die orifice into the zone of lower pressure, and 4) allowing the ejected foamable polymer composition to expand, under the influence of the blowing agent, to form the foam, including each of Foams 1 ¨ 6 and each of foams Fl ¨ F8.
The present invention also can use continuous processes for forming the foam.
By way of example such a continuous process involves forming a foamable PEF
composition, including each of FC1 ¨ FC8, and then expanding that foamable PEF
composition without substantial interruption. For example, a foamable PEF
composition, including each of FC1 ¨ FC8, may be prepared in an extruder by heating the selected PEF polymer resin, including each of TPP1 ¨ TPP6, to form a PEF melt, incorporating into the PEF melt a blowing agent of the present invention, including each of Blowing Agents 1 ¨ 31, preferably by solubilizing the blowing agent into the PEF melt, at an initial pressure to form a foamable PEF composition comprising a substantially homogeneous combination of PEF and blowing agent, including each of FC1 ¨ FC8, and then extruding that foamable PEF composition through a die into a zone at a selected foaming pressure and allowing the foamable PEF composition to expand into a CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) foam, including each of Foams 1 ¨6 and each of foams Fl ¨ F8 described below, under the influence of the blowing agent. Optionally, the foamable PEF composition which comprises the PEF polymer, including each of FC1 ¨ FC8, and the incorporated blowing agent, including each of Blowing Agents 1 ¨ 31, may be cooled prior to extruding the composition through the die to enhance certain desired properties of the resulting foam, including each of Foams 1 ¨ 6 and each of foams Fl ¨ F8.
The methods can be carried out, by way of example, using extrusion equipment of the general type disclosed in Figure 1. In particular, the extrusion apparatus can include a raw material feed hopper 10 for holding the PEF polymer 15 of the present invention, including each of TPP1 ¨ TPP6, and one or more optional components (which may be added with the PEF in the hopper or optionally elsewhere in the process depending on the particular needs of the user). The feed materials 15, excluding the blowing agent, can be charged to the hopper and delivered to the screw extruder 10.
The extruder 20 can include thermocouples (not shown) located at three points along the length thereof and a pressure sensor (not shown) at the discharge end 20A
of the extruder. A mixer section 30 can be located at the discharge end 20A of the extruder for receiving blowing agent components of the present invention, including each of Blowing Agents 1 ¨ 31, via one or more metering pumps 40A and 40B and mixing those blowing agents into the PEF melt in the mixer section. Sensors (not shown) can be included for monitoring the temperature and pressure of the mixer section 30.
The mixer section 30 can then discharge the foamable composition melt of the present invention, including each of FC1 ¨ FC8, into a pair of melt coolers 50 oriented in series, with temperature sensors (not shown) located in each cooler to monitor the melt temperature. The melt is then extruded through a die 60, which also had temperature and pressure sensors (not shown) for monitoring the pressure and temperature at the die. The die pressure and temperature can be varied, according to the needs of each particular extrusion application to produce a foam 70 of the present invention, including each of including each of Foams 1 ¨ 6 and each of foams Fl ¨ F8 described below. The foam can then be carried away from the extrusion equipment by a conveyor belt 80.
The foamable polymer compositions of the present invention, including each of FC1 ¨ FC8, may optionally contain additional additives such as nucleating agents, cell-CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) controlling agents, glass and carbon fibers, dyes, pigments, fillers, antioxidants, extrusion aids, stabilizing agents, antistatic agents, fire retardants, IR
attenuating agents and thermally insulating additives. Nucleating agents include, among others, materials such as talc, calcium carbonate, sodium benzoate, and chemical blowing agents such azodicarbonamide or sodium bicarbonate and citric acid.
IR attenuating agents and thermally insulating additives can include carbon black, graphite, silicon dioxide, metal flake or powder, among others. Flame retardants can include, among others, brominated materials such as hexabromocyclodecane and polybrominated biphenyl ether. Each of the above-noted additional optional additives can be introduced into the foam at various times and that various locations in the process according to known techniques, and all such additives and methods of addition or within the broad scope of the present invention.

Although applicant is not bound by any theory of operation, it is believed that one or more of the advantageous foam properties of the present invention arise, at least in part, as a result of the ability to form foams with high closed cell content.

Comparative Example 1 ¨ PEF FOAM PREPARATION USING PEX1 AND CO2 AS
BLOWING AGENT
1 gram of PEX1 in a glass container was loaded into a 60 cc autoclave and then dried under vacuum for six (6) hours at 130 C. The dried polymer was then cooled to room temperature and placed in a glass container inside an autoclave. About 0.25 moles (11 grams) of CO2 blowing agent was then pumped into the autoclave containing the dried polymer, and CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) then the autoclave was heated to bring the polymer to a melt state at a temperature of about 240 C and a pressure above about 610 psig. The polymer/CO2blowing agent was maintained in this melt state for about 1 hour and the temperature and pressure of the melt/blowing agent was then reduced over a period of about 5¨ 15 minutes to about 190 C and 610 psig (hereinafter referred to for convenience as pre-foaming temperature and pre-foaming pressure, respectively), and then maintained at about this temperature and pressure for a period of about 30 minutes to allow the amount of blowing agent incorporated into the melt under such conditions to reach equilibrium. The temperature and pressure in the autoclave were then reduced rapidly (over a period of about 10 seconds for the pressure reduction and about 1 ¨ 10 minutes for the temperature reduction using chilled water)) to ambient conditions (approximately 22 C and 1 atmosphere) and foaming occurred. The foam thus produced was tested to determine the following properties:
= compressive strength ("CS") (measured perpendicular to the plane (that was in direct contact with the blowing agent) in accordance with ISO 844) = compressive modulus ("CM") (measured perpendicular to the plane (that was in direct contact with the blowing agent) in accordance with ISO 844) = tensile strength ("TS") (measured perpendicular to the plane (that was in direct contact with the blowing agent) in accordance with ASTM 0297) = tensile modulus ("TM") (measured perpendicular to the plane (that was in direct contact with the blowing agent) in accordance with ASTM C297) = relative foam density ("RFD").
As used herein, RFD is the density of the foam produced divided by the density of the starting polymer. Density is measured in these Examples using a method which corresponds generally to ASTM D71, except that hexane is used for displacement instead of water.
The foam produced in this Comparative Example 1 was tested and found to have the properties as reported in Table Cl below:
TABLE Cl RFD 0.25 TS, Megapascal (Mpa) 0.74 CS, Mpa 0.5 TM, Mpa 32 CM, Mpa 8 CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) As reported above, the foam made using CO2 under the reported conditions had an RFD
of 0.25, that is, a density that was only 25% of the density of the starting polymer. This is a foam density that is too high for many important applications.
Examples 2 ¨ 4 - PEF FOAM PREPARATION USING PEX1 AND
trans-1234ze, trans-1233zd and trans-1336mzz as BLOWING AGENT
Comparative Example 1 was repeated, except the CO2 blowing agent was replaced, on a molar equivalent basis in a separate run with each of trans-1234ze, trans-1233zd and trans-1336mzz, with the pre-foaming pressure for each run being maintained within a similar pre-foaming pressure (not more than about 50 psig greater than the 610 psig pre-foaming pressure used in Comparative Example 1). The foams thus produced were observed to be good, high-quality foam, and were then tested and found to have the properties reported in Table E2-4 below:

Thus, for example, the tensile strength using trans-1234z blowing agent in Example 4 is 6.08 times greater than the tensile strength measured in Example 2. Tensile properties were determined based on and compressive properties were determined based on ASTM C365 and ASTM
844.
As can be seen from the results reported in Table E2 ¨4 above, each of the HFO
compounds tested as blowing agents produced a foam that had a dramatically and unexpectedly improved density compared to CO2, that is, in each case the density of the foam produced with the tested HFO resulted in density value that is at least about 1.9 times less than the density of the CO2 blown foam. Furthermore, from among the foams produced, the trans-1234ze produced a foam that was more than 3.5 times less than the density of the CO2 blown CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) foam, and the use of the trans-1234ze also unexpectedly produced a foam that was dramatically superior to even the other HFO blowing agents in terms of the important tensile properties, with the 1234ze foam being at least 2.7 times better in tensile strength than the 1233zd foam.
The foam formed with 1234ze(E) in Example 4A produced a high-quality, low-density foam with an excellent uniform distribution of cells, as illustrated in Figure 2. Figure 2 is an SEM micrograph of a thin slice of the foam produced, thus showing cell walls having been removed from the side of the cell facing the viewer, allowing visibility into the cell, and showing that well-formed closed cells comprise the foam.
Example 5 - PEF FOAM PREPARATION USING PEX1 AND cis1224yd as BLOWING
AGENT
Comparative Example 1 was repeated, except the CO2 blowing agent was replaced in the process with cis1224yd and the process conditions were modified in a manner to produce a foam having within an amount of moles of blowing agent in the foam that is within 15% of the moles of blowing agent in Comparative Example 1. In particular, the foam thus produced using cis1224yd according to this Example was observed to be an acceptable foam and to have an RFD that was within about 15 relative percent of the RFD produced using CO2 in Comparative Example 1, and therefore the foam of this example had a density that is too high for many important applications. However, for applications for which it is acceptable to have such a density, the foam produced in this Example was tested compared to CO2 and was found to be dramatically superior in the strength and modulus properties, as reported in Table E5 below:

As can be seen from TABLE E5 above, on an equivalent molar blowing agent basis (i.e., within 15%), the foams made using cis1224yd were surprisingly superior to the foam made using CO2 based on each of the physical strength and modulus properties tested. For example, CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) the foam made with ci51224yd produced a foam with both tensile and compressive modulus that is twice the value produced using CO2, while at the same time having compressive and tensile strengths that are more than 60% better than CO2. This result is unexpected.
Example 6- PEF FOAM PREPARATION USING PEX1 AND trans-1234ze as BLOWING AGENT
Comparative Example 1 was repeated, except: (1) the CO2 blowing agent was replaced with trans-1234ze and with an increase in molar amount of the trans-1234ze (by about 2.5 more moles than Comparative Example 1) to raise the pre-foaming pressure to 1590 psig. The foam thus produced was observed to be a good, high-quality foam, and was then tested and found to have the properties reported in Table E6 below (with the value of the mechanical properties again being reported as a ratio of the values for 1233zd in Example 2 as baseline of 1):

SHEET (RULE 26) Examples 10 and 11 - PEF FOAM PREPARATION USING PEX9 and 1234yf and trans-1234ze as BLOWING AGENT
PEX9 was processed in two runs in an autoclave according to essentially the same procedure described in Comparative Example 1 except that 1234yf and trans1234ze (respectively Example 10 and Example 11) were each used as the blowing agent and except as noted below.

processing. It is believed that, in view of the disclosures contained herein, including the polymer synthesis described in the Examples below, a person skilled in the art will be able to produce PEF polymers within the range of characteristics described in the table above and elsewhere herein.
An example of the process for chain extension treatment of polyesters is provided in the article "Recycled poly(ethylene terephthalate) chain extension by a reactive extrusion process,"

As explained in US 1009/0264545, which is incorporated herein by reference, chain extenders generally are typically compounds that are at least di-functional with respect to reactive groups which can CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) react with end groups or functional groups in the polyester to extend the length of the polymer chains. In certain cases, as disclosed herein, such a treatment can advantageously increases the average molecular weight of the polyester to improve its melt strength and/or other important properties. The degree of chain extension achieved is related, at least in part, to the structure and functionalities of the compounds used. Various compounds are useful as chain extenders. Non-limiting examples of chain extenders include trimellitic anhydride, pyromellitic dianhydride (PMDA), trimellitic acid, haloformyl derivatives thereof, or compounds containing multi-functional epoxy (e.g., glycidyl), or oxazoline functional groups.
Nanocomposite material such as finely dispersed nanoclay may optionally be used for controlling viscosity.
Commercial chain extenders include CESA-Extend from Clariant, Joncryl from BASF, or Lotader from Arkema. The amount of chain extender can vary depending on the type and molecular weight of the polyester components. The amount of chain extender used to treat the polymer can vary widely, and in preferred embodiments ranges from about 0.1 to about 5 wt. %, or preferably from about 0.1 to about 1.5 wt. %. Examples of chain extenders are also described in U.S. Pat. No. 4,219,527, which is incorporated herein by reference.
An example of the process for SSP processing of poly(ethylene furanoate) is provided in the article "Solid-State Polymerization of Poly(ethylene furanoate) Biobased Polyester, I: Effect of Catalyst Type on Molecular Weight Increase,' Nejib Kasmi, Mustapha Majdoub, George Z. Papageorgiou, Dimitris S. Achilias, and Dimitrios N.

For clarity, it will be noted that definition of the foams in the Table below all begin with only the letter F, in contrast to the foams defined by the paragraphs in the summary above, which begin with the capitalized word Foam.
In general, the forming step involves first introducing into a PEF polymer of the present invention, including each of TPP1 ¨ TPP6, a blowing agent of the present invention, including each of Blowing Agents 1 ¨ 31, to form a foamable PEF
composition comprising PEF and blowing agent. One example of a preferred method for forming a foamable PEF composition of the present invention is to plasticize the PEF, preferably comprising heating the PEF to its melt temperature, preferably above its melt temperature, and thereafter exposing the PEF melt to the blowing agent under conditions effective to incorporate (preferably by solubilizing) the desired amount of blowing agent into the polymer melt.
In preferred embodiments, the foaming methods of the present invention comprise providing a foamable composition of the present invention, including each of FC1 ¨ FC8 and foaming the provided foamable composition. In preferred embodiments, the foaming methods of the present invention comprising providing a foamable composition of the present invention, including each of FC1 ¨ FC8, and extruding the provided foamable composition to form a foam of the present invention, including each of Foams 1 ¨ 6 and each of foams Fl ¨ F8.
Foaming processes of the present invention can include batch, semi-batch, continuous processes, and combinations of two or more of these. Batch processes generally involve preparation of at least one portion of the foamable polymer composition, including each of FC1 ¨ FC8, in a storable state and then using that portion of foamable polymer composition at some future point in time to prepare a foam.
Semi-batch process involves preparing at least a portion of a foamable polymer CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) composition, including each of FC1 ¨ FC8, and intermittently expanding that foamable polymer composition into a foam including each of Foams 1 ¨6 and each of foams Fl ¨
F8, all in a single process. For example, U.S. Pat. No. 4,323,528, herein incorporated by reference, discloses a process for making thermoplastic foams via an accumulating extrusion process. The present invention thus includes processes that comprises: 1) mixing PEF thermoplastic polymer, including each of TPP1 ¨ TP P6, and a blowing agent of the present invention, including each of Blowing Agents 1 ¨ 31, under conditions to form a foamable PEF composition; 2) extruding the foamable PEF
composition, including each of FC1 ¨ FC8, into a holding zone maintained at a temperature and pressure which does not allow the foamable composition to foam, where the holding zone preferably comprises a die defining an orifice opening into a zone of lower pressure at which the foamable polymer composition, including each of FC1 ¨ FC8, foams and an openable gate closing the die orifice; 3) periodically opening the gate while substantially concurrently applying mechanical pressure by means of a movable ram on the foamable polymer composition, including each of FC1 ¨ FC8, to eject it from the holding zone through the die orifice into the zone of lower pressure, and 4) allowing the ejected foamable polymer composition to expand, under the influence of the blowing agent, to form the foam, including each of Foams 1 ¨ 6 and each of foams Fl ¨ F8.
The present invention also can use continuous processes for forming the foam.
By way of example such a continuous process involves forming a foamable PEF
composition, including each of FC1 ¨ FC8, and then expanding that foamable PEF
composition without substantial interruption. For example, a foamable PEF
composition, including each of FC1 ¨ FC8, may be prepared in an extruder by heating the selected PEF polymer resin, including each of TPP1 ¨ TPP6, to form a PEF melt, incorporating into the PEF melt a blowing agent of the present invention, including each of Blowing Agents 1 ¨ 31, preferably by solubilizing the blowing agent into the PEF melt, at an initial pressure to form a foamable PEF composition comprising a substantially homogeneous combination of PEF and blowing agent, including each of FC1 ¨ FC8, and then extruding that foamable PEF composition through a die into a zone at a selected foaming pressure and allowing the foamable PEF composition to expand into a CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) foam, including each of Foams 1 ¨6 and each of foams Fl ¨ F8 described below, under the influence of the blowing agent. Optionally, the foamable PEF composition which comprises the PEF polymer, including each of FC1 ¨ FC8, and the incorporated blowing agent, including each of Blowing Agents 1 ¨ 31, may be cooled prior to extruding the composition through the die to enhance certain desired properties of the resulting foam, including each of Foams 1 ¨ 6 and each of foams Fl ¨ F8.
The methods can be carried out, by way of example, using extrusion equipment of the general type disclosed in Figure 1. In particular, the extrusion apparatus can include a raw material feed hopper 10 for holding the PEF polymer 15 of the present invention, including each of TPP1 ¨ TPP6, and one or more optional components (which may be added with the PEF in the hopper or optionally elsewhere in the process depending on the particular needs of the user). The feed materials 15, excluding the blowing agent, can be charged to the hopper and delivered to the screw extruder 10.
The extruder 20 can include thermocouples (not shown) located at three points along the length thereof and a pressure sensor (not shown) at the discharge end 20A
of the extruder. A mixer section 30 can be located at the discharge end 20A of the extruder for receiving blowing agent components of the present invention, including each of Blowing Agents 1 ¨ 31, via one or more metering pumps 40A and 40B and mixing those blowing agents into the PEF melt in the mixer section. Sensors (not shown) can be included for monitoring the temperature and pressure of the mixer section 30.
The mixer section 30 can then discharge the foamable composition melt of the present invention, including each of FC1 ¨ FC8, into a pair of melt coolers 50 oriented in series, with temperature sensors (not shown) located in each cooler to monitor the melt temperature. The melt is then extruded through a die 60, which also had temperature and pressure sensors (not shown) for monitoring the pressure and temperature at the die. The die pressure and temperature can be varied, according to the needs of each particular extrusion application to produce a foam 70 of the present invention, including each of including each of Foams 1 ¨ 6 and each of foams Fl ¨ F8 described below. The foam can then be carried away from the extrusion equipment by a conveyor belt 80.
The foamable polymer compositions of the present invention, including each of FC1 ¨ FC8, may optionally contain additional additives such as nucleating agents, cell-CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) controlling agents, glass and carbon fibers, dyes, pigments, fillers, antioxidants, extrusion aids, stabilizing agents, antistatic agents, fire retardants, IR

Although applicant is not bound by any theory of operation, it is believed that one or more of the advantageous foam properties of the present invention arise, at least in part, as a result of the ability to form foams with high closed cell content.

Comparative Example 1 ¨ PEF FOAM PREPARATION USING PEX1 AND CO2 AS
BLOWING AGENT
1 gram of PEX1 in a glass container was loaded into a 60 cc autoclave and then dried under vacuum for six (6) hours at 130 C. The dried polymer was then cooled to room temperature and placed in a glass container inside an autoclave. About 0.25 moles (11 grams) of CO2 blowing agent was then pumped into the autoclave containing the dried polymer, and CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) then the autoclave was heated to bring the polymer to a melt state at a temperature of about 240 C and a pressure above about 610 psig. The polymer/CO2blowing agent was maintained in this melt state for about 1 hour and the temperature and pressure of the melt/blowing agent was then reduced over a period of about 5¨ 15 minutes to about 190 C and 610 psig (hereinafter referred to for convenience as pre-foaming temperature and pre-foaming pressure, respectively), and then maintained at about this temperature and pressure for a period of about 30 minutes to allow the amount of blowing agent incorporated into the melt under such conditions to reach equilibrium. The temperature and pressure in the autoclave were then reduced rapidly (over a period of about 10 seconds for the pressure reduction and about 1 ¨ 10 minutes for the temperature reduction using chilled water)) to ambient conditions (approximately 22 C and 1 atmosphere) and foaming occurred. The foam thus produced was tested to determine the following properties:
= compressive strength ("CS") (measured perpendicular to the plane (that was in direct contact with the blowing agent) in accordance with ISO 844) = compressive modulus ("CM") (measured perpendicular to the plane (that was in direct contact with the blowing agent) in accordance with ISO 844) = tensile strength ("TS") (measured perpendicular to the plane (that was in direct contact with the blowing agent) in accordance with ASTM 0297) = tensile modulus ("TM") (measured perpendicular to the plane (that was in direct contact with the blowing agent) in accordance with ASTM C297) = relative foam density ("RFD").
As used herein, RFD is the density of the foam produced divided by the density of the starting polymer. Density is measured in these Examples using a method which corresponds generally to ASTM D71, except that hexane is used for displacement instead of water.
The foam produced in this Comparative Example 1 was tested and found to have the properties as reported in Table Cl below:
TABLE Cl RFD 0.25 TS, Megapascal (Mpa) 0.74 CS, Mpa 0.5 TM, Mpa 32 CM, Mpa 8 CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) As reported above, the foam made using CO2 under the reported conditions had an RFD
of 0.25, that is, a density that was only 25% of the density of the starting polymer. This is a foam density that is too high for many important applications.
Examples 2 ¨ 4 - PEF FOAM PREPARATION USING PEX1 AND
trans-1234ze, trans-1233zd and trans-1336mzz as BLOWING AGENT
Comparative Example 1 was repeated, except the CO2 blowing agent was replaced, on a molar equivalent basis in a separate run with each of trans-1234ze, trans-1233zd and trans-1336mzz, with the pre-foaming pressure for each run being maintained within a similar pre-foaming pressure (not more than about 50 psig greater than the 610 psig pre-foaming pressure used in Comparative Example 1). The foams thus produced were observed to be good, high-quality foam, and were then tested and found to have the properties reported in Table E2-4 below:

Thus, for example, the tensile strength using trans-1234z blowing agent in Example 4 is 6.08 times greater than the tensile strength measured in Example 2. Tensile properties were determined based on and compressive properties were determined based on ASTM C365 and ASTM
844.
As can be seen from the results reported in Table E2 ¨4 above, each of the HFO
compounds tested as blowing agents produced a foam that had a dramatically and unexpectedly improved density compared to CO2, that is, in each case the density of the foam produced with the tested HFO resulted in density value that is at least about 1.9 times less than the density of the CO2 blown foam. Furthermore, from among the foams produced, the trans-1234ze produced a foam that was more than 3.5 times less than the density of the CO2 blown CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) foam, and the use of the trans-1234ze also unexpectedly produced a foam that was dramatically superior to even the other HFO blowing agents in terms of the important tensile properties, with the 1234ze foam being at least 2.7 times better in tensile strength than the 1233zd foam.
The foam formed with 1234ze(E) in Example 4A produced a high-quality, low-density foam with an excellent uniform distribution of cells, as illustrated in Figure 2. Figure 2 is an SEM micrograph of a thin slice of the foam produced, thus showing cell walls having been removed from the side of the cell facing the viewer, allowing visibility into the cell, and showing that well-formed closed cells comprise the foam.
Example 5 - PEF FOAM PREPARATION USING PEX1 AND cis1224yd as BLOWING
AGENT
Comparative Example 1 was repeated, except the CO2 blowing agent was replaced in the process with cis1224yd and the process conditions were modified in a manner to produce a foam having within an amount of moles of blowing agent in the foam that is within 15% of the moles of blowing agent in Comparative Example 1. In particular, the foam thus produced using cis1224yd according to this Example was observed to be an acceptable foam and to have an RFD that was within about 15 relative percent of the RFD produced using CO2 in Comparative Example 1, and therefore the foam of this example had a density that is too high for many important applications. However, for applications for which it is acceptable to have such a density, the foam produced in this Example was tested compared to CO2 and was found to be dramatically superior in the strength and modulus properties, as reported in Table E5 below:
Ex Blowing RFD Avg. RELATIVE MECHANICAL PROPERTIES*

As can be seen from TABLE E5 above, on an equivalent molar blowing agent basis (i.e., within 15%), the foams made using cis1224yd were surprisingly superior to the foam made using CO2 based on each of the physical strength and modulus properties tested. For example, CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) the foam made with ci51224yd produced a foam with both tensile and compressive modulus that is twice the value produced using CO2, while at the same time having compressive and tensile strengths that are more than 60% better than CO2. This result is unexpected.
Example 6- PEF FOAM PREPARATION USING PEX1 AND trans-1234ze as BLOWING AGENT
Comparative Example 1 was repeated, except: (1) the CO2 blowing agent was replaced with trans-1234ze and with an increase in molar amount of the trans-1234ze (by about 2.5 more moles than Comparative Example 1) to raise the pre-foaming pressure to 1590 psig. The foam thus produced was observed to be a good, high-quality foam, and was then tested and found to have the properties reported in Table E6 below (with the value of the mechanical properties again being reported as a ratio of the values for 1233zd in Example 2 as baseline of 1):

The polymer/blowing agent was then heated (without pre-drying the polymer) to a melt state at a temperature of about 240 C and a pressure of about 2380 psig in the case of 1234yf as the blowing agent and of about 2250 psig in the case of trans1234ze as the blowing agent, and then the polymer/blowing agent was maintained in this melt state for about 1 hour.

Examples 21 -22 PEF FOAM PREPARATION USING PEX1 AND BLOWING AGENT
CONSISTING OF trans-1234ze AND CO-BLOWING AGENTS
Example 4 is repeated in a series of runs, except that in each run the blowing agent consisting of 0.25 moles of trans1234ze used in Example 4 is replaced by a combination consisting of about 0.125 moles of trans1234ze and 0.125 moles of a co-blowing agent. The blowing agent combinations used in each of Examples 21 ¨ 22 are shown in Table E21-22, with the relative mechanical property results being presented in this table based on the result from Example 4 as the base line of 1.

By way of example, the tensile modulus of the foam blowing with cyclopentane co-blowing agent is only about 3% of the tensile modulus achieved by trans1234ze alone, and every mechanical property measured in Example 21 is 20% or less than the value achieved by Example 4.
Comparative Example 2¨ PEF FOAM PREPARATION USING PEX1 AND HFC-134a AS BLOWING AGENT
1 gram of PEX1 in a glass container was loaded into an autoclave and then dried for under vacuum for six (6) hours at 130 C. The dried polymer was then cooled to room temperature and placed in a glass container inside an autoclave. About 0.25 moles (25.3 CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) grams) of R-134a blowing agent was then pumped into the autoclave containing the dried polymer, and then the autoclave was heated to bring the polymer to a melt state at a temperature of about 240 C and a pressure above about 570 psig. The polymer/R134a blowing agent was maintained in this melt state for about 1 hour and the temperature and pressure of the melt/blowing agent was then reduced over a period of about 5 ¨ 15 minutes to about 190 C
and 570 psig (hereinafter referred to for convenience as pre-foaming temperature and pre-foaming pressure, respectively), and then maintained at about this temperature and pressure for a period of about 30 minutes to allow the amount of blowing agent incorporated into the melt under such conditions to reach equilibrium. The temperature and pressure in the autoclave were then reduced rapidly (over a period of about 10 seconds for the pressure reduction and about 1 ¨ 10 minutes for the temperature reduction using chilled water)) to ambient conditions (approximately 22 C and 1 atmosphere) and foaming occurred. The foam thus produced had a relatively acceptable foam structure and was tested to determine relative foam density (RFD) and strength and modulus properties. The RFD of the foam was 0.12.
Example 23- PEF FOAM PREPARATION USING PEX1 AND trans-1336mzz as BLOWING AGENT
Comparative Example 2 was repeated, except: (i) the HFC-134a blowing agent was replaced in the process with trans1336mmzz in two separate runs; and (ii) the process conditions were modified in a manner to produce a foam having a density similar to the density of the foam produced in Comparative Example 2. In particular, the foams thus produced using trans1336mzz according to this Example were observed to be acceptable foams and had RFD
values that were within about 15% of the RFD produced using HFC-134a in Comparative Example 2. The foams produced were tested to determine various properties, including strength and modulus properties, and were found to be dramatically superior to the foam made with HFC-134a in each of the measured properties, as reported in Table E23 below:

As can be seen from TABLE E23 above, the foams made using trans1336mzz were surprisingly and dramatically superior to the foam made using HFC-134a in terms of all the physical strength and modulus properties tested. For example, the foam made with trans1336mzz produced a foam with both tensile and compressive strengths that were more than 10 times better than the strength of foam made with HFC-134a, while at the same time having compressive and tensile modulus that are more 3 times better than foam made using HFC-134a. This result shows a dramatic and unexpected improvement in physical properties of the foam.
Comparative Example 3¨ PEF FOAM PREPARATION USING PEX1 AND
ISOPENTANE AS BLOWING AGENT
1 gram of PEX1 in a glass container was loaded into an autoclave and then dried for under vacuum for six (6) hours at 130 C. The dried polymer was then cooled to room temperature and placed in a glass container inside an autoclave. About 0.25 moles (27.8 grams) of isopentane blowing agent was then pumped into the autoclave containing the dried polymer, and then the autoclave was heated to bring the polymer to a melt state at a temperature of about 240 C and a pressure above about 443 psig. The polymer/isopentane blowing agent was maintained in this melt state for about 1 hour and the temperature and pressure of the melt/blowing agent was then reduced over a period of about 5 ¨
15 minutes to about 190 C and 443 psig (hereinafter referred to for convenience as pre-foaming temperature and pre-foaming pressure, respectively), and then maintained at about this temperature and pressure for a period of about 30 minutes to allow the amount of blowing agent incorporated into the melt under such conditions to reach equilibrium. The temperature and pressure in the autoclave were then reduced rapidly (over a period of about 10 seconds for the pressure reduction and about 1 ¨ 10 minutes for the temperature reduction using chilled water)) to ambient conditions (approximately 22 C and 1 atmosphere) and foaming occurred.
The foam thus produced had a relatively acceptable foam structure and was tested to determine relative foam density (RFD) and strength and modulus properties. The RFD of the foam was 0.13.

1 gram of PEX1 in a glass container was loaded into an autoclave and then dried for under vacuum for six (6) hours at 130 C. The dried polymer was then cooled to room temperature and placed in a glass container inside an autoclave. About 0.25 moles (32.9 grams) of cyclopentane blowing agent was then pumped into the autoclave containing the dried polymer, and then the autoclave was heated to bring the polymer to a melt state at a temperature of about 240 C and a pressure above about 320 psig. The polymer/cyclopentane blowing agent combination was maintained in this melt state for about 1 hour, and the temperature and pressure of the melt/blowing agent were then reduced over a period of about 5 ¨ 15 minutes to about 190 C and 320 psig (hereinafter referred to for convenience as pre-foaming temperature and pre-foaming pressure, respectively), and then maintained at about this temperature and pressure for a period of about 30 minutes to allow the amount of blowing agent incorporated into the melt under such conditions to reach equilibrium. The temperature and pressure in the autoclave were then reduced rapidly (over a period of about 10 seconds for the pressure reduction and about 1 ¨ 10 minutes for the temperature reduction using chilled water)) to ambient conditions (approximately 22 C and 1 atmosphere) and foaming occurred. The foam thus produced had a relatively acceptable foam structure and was tested to determine relative foam density (RFD) and strength and modulus properties. The RFD of the foam was 0.2.

For example, the foam made with cis1224yd produced a foam with a tensile strength more than 2 times better than the values achieved using cyclopentane.

The polymer/CO2blowing agent was maintained in this melt state for about 1 hour and the temperature and pressure of the melt/blowing agent was then reduced over a period of about 5-15 minutes to about 180 C and 242 psig (hereinafter referred to for convenience as pre-foaming temperature and pre-foaming pressure, respectively), and then maintained at about this temperature and pressure for a period of about 30 minutes to allow the amount of blowing agent incorporated into the melt under such conditions to reach equilibrium.
The temperature and pressure in the autoclave were then reduced rapidly (over a period of about 10 seconds for the pressure reduction and about 1 ¨ 10 minutes for the temperature reduction using chilled water)) to ambient conditions (approximately 22 C and 1 atmosphere) and foaming occurred. The foam thus produced had a relatively acceptable foam structure and was tested to determine density, strength and modulus properties using the same procedure as described in Comparative Example 1. The foam produced in this Comparative Example 5 had an RFD of 0.09.
Example 29 - 31 - PEF FOAM PREPARATION USING PEX31 AND trans1234ze as BLOWING AGENT
Comparative Example 5 was repeated, except the CO2 blowing agent was replaced in the process with trans1234ze in three separate runs. The foam thus produced using trans1234ze according to this Example was observed to be an acceptable foam and to have an RFD that was within about 15 relative percent of the RFD produced using CO2 in Comparative Example 5. The foams produced were tested to determine various properties, including strength and modulus properties, and were found to be dramatically superior in each of the measured properties, as reported in Table E29-31 below:

For example, the foam made with trans1234ze produced a foam with both tensile and compressive modulus that is at least 4 times the value produced using CO2. This result is unexpected.

Two homopolymers of PEF were with polymer molecular weights of about 75,000 g/mol and about 91,000 g/mol. In particular, the 75 kg/mol PEF homopolymer was formed by esterification and polycondensation of 350 grams of 2,5-furandicarboxylic acid (FDCA) with 279 grams of mono-ethylene glycol (EG). The reactants were added to a 1-liter cylindrical steel reactor equipped with an overhead stirrer and a distillation/condensation apparatus. After pulling vacuum and back filling with nitrogen, 0.288 gram of titanium (IV) isopropoxide catalyst was added to the flask. The flask was then lowered into a 180 C salt bath and overhead mixing was started at 200 rpm under a nitrogen atmosphere. After 2.5 hours, the bath temperature was increased to 210 C. After 30 minutes at this temperature under nitrogen, vacuum was started. After 40 minutes under vacuum, the temperature was increased to 230 C and was continued for 1 hour. Under a stream of nitrogen, PMDA (2.73 g ¨ 0.7% by weight) was slowly added over the span of about 5 minutes. An additional 30 minutes of mixing at temperature were allowed before stopping the reaction. To perform SSP, an aliquot (30 g) of the product was ground and heated at 180 C under vacuum for 3 days on a rotary evaporator to produce the PEF
hornopolymer as reported below.
For the 90.8 kg/mol MW polymer, FDCA (75 g) and EG (59.6 g) were added to a 500 mL
cylindrical steel reactor equipped with an overhead stirrer and a distillation/condensation apparatus. After pulling vacuum and back filling with nitrogen, 0.100 gram of titanium (IV) isopropoxide catalyst was added to the flask. The flask was then lowered into a 180 C salt bath and overhead mixing was started at 200 rpm under a nitrogen atmosphere. After 2.5 hours, the bath temperature was increased to 210 C. After 30 minutes at this temperature under nitrogen, vacuum was started. After 40 min under vacuum, the temperature was increased to 250 C and was continued for 2 hours. Under a stream of nitrogen, PM DA (0.587 g) was slowly added over the span of about 5 minutes. The reaction was stopped after an additional 30 minutes of mixing at temperature. The product was removed from the vessel. Gamma-valerolactone was added to dissolve the polymer that was remaining in the reactor and on the impeller.
The mixture was CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) stirred for several hours at 190 C. The gamma-valerolactone was distilled from the polymer under vacuum resulting in a solid. To perform SSP, an aliquot (30 g) of the product was ground and heated at 180 C under vacuum for 3 days on a rotary evaporator to produce the PEF
homopolymer as reported below. The polymer was then subject to solid state polymerization according to known techniques to produce the PEF homopolymer as reported below.
The PEF polymers thus produced were tested using the measurement protocols as described above and found to have the characteristics reported in Table E44 below:

The blowing agent combinations used in each of Examples 21 ¨ 22 are shown in Table E21-22, with the relative mechanical property results being presented in this table based on the result from Example 4 as the base line of 1.

By way of example, the tensile modulus of the foam blowing with cyclopentane co-blowing agent is only about 3% of the tensile modulus achieved by trans1234ze alone, and every mechanical property measured in Example 21 is 20% or less than the value achieved by Example 4.
Comparative Example 2¨ PEF FOAM PREPARATION USING PEX1 AND HFC-134a AS BLOWING AGENT
1 gram of PEX1 in a glass container was loaded into an autoclave and then dried for under vacuum for six (6) hours at 130 C. The dried polymer was then cooled to room temperature and placed in a glass container inside an autoclave. About 0.25 moles (25.3 CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) grams) of R-134a blowing agent was then pumped into the autoclave containing the dried polymer, and then the autoclave was heated to bring the polymer to a melt state at a temperature of about 240 C and a pressure above about 570 psig. The polymer/R134a blowing agent was maintained in this melt state for about 1 hour and the temperature and pressure of the melt/blowing agent was then reduced over a period of about 5 ¨ 15 minutes to about 190 C
and 570 psig (hereinafter referred to for convenience as pre-foaming temperature and pre-foaming pressure, respectively), and then maintained at about this temperature and pressure for a period of about 30 minutes to allow the amount of blowing agent incorporated into the melt under such conditions to reach equilibrium. The temperature and pressure in the autoclave were then reduced rapidly (over a period of about 10 seconds for the pressure reduction and about 1 ¨ 10 minutes for the temperature reduction using chilled water)) to ambient conditions (approximately 22 C and 1 atmosphere) and foaming occurred. The foam thus produced had a relatively acceptable foam structure and was tested to determine relative foam density (RFD) and strength and modulus properties. The RFD of the foam was 0.12.

In particular, the foams thus produced using trans1336mzz according to this Example were observed to be acceptable foams and had RFD
values that were within about 15% of the RFD produced using HFC-134a in Comparative Example 2. The foams produced were tested to determine various properties, including strength and modulus properties, and were found to be dramatically superior to the foam made with HFC-134a in each of the measured properties, as reported in Table E23 below:

As can be seen from TABLE E23 above, the foams made using trans1336mzz were surprisingly and dramatically superior to the foam made using HFC-134a in terms of all the physical strength and modulus properties tested. For example, the foam made with trans1336mzz produced a foam with both tensile and compressive strengths that were more than 10 times better than the strength of foam made with HFC-134a, while at the same time having compressive and tensile modulus that are more 3 times better than foam made using HFC-134a. This result shows a dramatic and unexpected improvement in physical properties of the foam.
Comparative Example 3¨ PEF FOAM PREPARATION USING PEX1 AND

1 gram of PEX1 in a glass container was loaded into an autoclave and then dried for under vacuum for six (6) hours at 130 C. The dried polymer was then cooled to room temperature and placed in a glass container inside an autoclave. About 0.25 moles (27.8 grams) of isopentane blowing agent was then pumped into the autoclave containing the dried polymer, and then the autoclave was heated to bring the polymer to a melt state at a temperature of about 240 C and a pressure above about 443 psig. The polymer/isopentane blowing agent was maintained in this melt state for about 1 hour and the temperature and pressure of the melt/blowing agent was then reduced over a period of about 5 ¨
15 minutes to about 190 C and 443 psig (hereinafter referred to for convenience as pre-foaming temperature and pre-foaming pressure, respectively), and then maintained at about this temperature and pressure for a period of about 30 minutes to allow the amount of blowing agent incorporated into the melt under such conditions to reach equilibrium. The temperature and pressure in the autoclave were then reduced rapidly (over a period of about 10 seconds for the pressure reduction and about 1 ¨ 10 minutes for the temperature reduction using chilled water)) to ambient conditions (approximately 22 C and 1 atmosphere) and foaming occurred.
The foam thus produced had a relatively acceptable foam structure and was tested to determine relative foam density (RFD) and strength and modulus properties. The RFD of the foam was 0.13.

1 gram of PEX1 in a glass container was loaded into an autoclave and then dried for under vacuum for six (6) hours at 130 C. The dried polymer was then cooled to room temperature and placed in a glass container inside an autoclave. About 0.25 moles (32.9 grams) of cyclopentane blowing agent was then pumped into the autoclave containing the dried polymer, and then the autoclave was heated to bring the polymer to a melt state at a temperature of about 240 C and a pressure above about 320 psig. The polymer/cyclopentane blowing agent combination was maintained in this melt state for about 1 hour, and the temperature and pressure of the melt/blowing agent were then reduced over a period of about 5 ¨ 15 minutes to about 190 C and 320 psig (hereinafter referred to for convenience as pre-foaming temperature and pre-foaming pressure, respectively), and then maintained at about this temperature and pressure for a period of about 30 minutes to allow the amount of blowing agent incorporated into the melt under such conditions to reach equilibrium. The temperature and pressure in the autoclave were then reduced rapidly (over a period of about 10 seconds for the pressure reduction and about 1 ¨ 10 minutes for the temperature reduction using chilled water)) to ambient conditions (approximately 22 C and 1 atmosphere) and foaming occurred. The foam thus produced had a relatively acceptable foam structure and was tested to determine relative foam density (RFD) and strength and modulus properties. The RFD of the foam was 0.2.

For example, the foam made with cis1224yd produced a foam with a tensile strength more than 2 times better than the values achieved using cyclopentane.

The PEF polymer was tested and found to have the following characteristics, using the same measurement techniques as described in Example 1:
Molecular Weight ¨ -4=33,000 Glass Transition Temperature ¨ 90.5 C
Melt Temperature - 224 C
Decomposition Temperature ¨ 341 C
Crystallinity - 45%
CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) The PEF polymer so produced is referred to in these Examples as PEX28.
Comparative Example 5¨ PEF FOAM PREPARATION USING PEX28 AND CO2 AS
BLOWING AGENT
1 gram of PEX28 in a glass container was loaded into an autoclave and then dried under vacuum for six (6) hours at 130 C. The dried polymer was then cooled to room temperature and placed in a glass container inside an autoclave. About 0.25 moles (11 grams) of CO2 blowing agent was then pumped into the autoclave containing the dried polymer, and then the autoclave was heated to bring the polymer to a melt state at a temperature of about 240 C and a pressure above about 242 psig. The polymer/CO2blowing agent was maintained in this melt state for about 1 hour and the temperature and pressure of the melt/blowing agent was then reduced over a period of about 5-15 minutes to about 180 C and 242 psig (hereinafter referred to for convenience as pre-foaming temperature and pre-foaming pressure, respectively), and then maintained at about this temperature and pressure for a period of about 30 minutes to allow the amount of blowing agent incorporated into the melt under such conditions to reach equilibrium.
The temperature and pressure in the autoclave were then reduced rapidly (over a period of about 10 seconds for the pressure reduction and about 1 ¨ 10 minutes for the temperature reduction using chilled water)) to ambient conditions (approximately 22 C and 1 atmosphere) and foaming occurred. The foam thus produced had a relatively acceptable foam structure and was tested to determine density, strength and modulus properties using the same procedure as described in Comparative Example 1. The foam produced in this Comparative Example 5 had an RFD of 0.09.
Example 29 - 31 - PEF FOAM PREPARATION USING PEX31 AND trans1234ze as BLOWING AGENT
Comparative Example 5 was repeated, except the CO2 blowing agent was replaced in the process with trans1234ze in three separate runs. The foam thus produced using trans1234ze according to this Example was observed to be an acceptable foam and to have an RFD that was within about 15 relative percent of the RFD produced using CO2 in Comparative Example 5. The foams produced were tested to determine various properties, including strength and modulus properties, and were found to be dramatically superior in each of the measured properties, as reported in Table E29-31 below:

For example, the foam made with trans1234ze produced a foam with both tensile and compressive modulus that is at least 4 times the value produced using CO2. This result is unexpected.

Two homopolymers of PEF were with polymer molecular weights of about 75,000 g/mol and about 91,000 g/mol. In particular, the 75 kg/mol PEF homopolymer was formed by esterification and polycondensation of 350 grams of 2,5-furandicarboxylic acid (FDCA) with 279 grams of mono-ethylene glycol (EG). The reactants were added to a 1-liter cylindrical steel reactor equipped with an overhead stirrer and a distillation/condensation apparatus. After pulling vacuum and back filling with nitrogen, 0.288 gram of titanium (IV) isopropoxide catalyst was added to the flask. The flask was then lowered into a 180 C salt bath and overhead mixing was started at 200 rpm under a nitrogen atmosphere. After 2.5 hours, the bath temperature was increased to 210 C. After 30 minutes at this temperature under nitrogen, vacuum was started. After 40 minutes under vacuum, the temperature was increased to 230 C and was continued for 1 hour. Under a stream of nitrogen, PMDA (2.73 g ¨ 0.7% by weight) was slowly added over the span of about 5 minutes. An additional 30 minutes of mixing at temperature were allowed before stopping the reaction. To perform SSP, an aliquot (30 g) of the product was ground and heated at 180 C under vacuum for 3 days on a rotary evaporator to produce the PEF
hornopolymer as reported below.
For the 90.8 kg/mol MW polymer, FDCA (75 g) and EG (59.6 g) were added to a 500 mL
cylindrical steel reactor equipped with an overhead stirrer and a distillation/condensation apparatus. After pulling vacuum and back filling with nitrogen, 0.100 gram of titanium (IV) isopropoxide catalyst was added to the flask. The flask was then lowered into a 180 C salt bath and overhead mixing was started at 200 rpm under a nitrogen atmosphere. After 2.5 hours, the bath temperature was increased to 210 C. After 30 minutes at this temperature under nitrogen, vacuum was started. After 40 min under vacuum, the temperature was increased to 250 C and was continued for 2 hours. Under a stream of nitrogen, PM DA (0.587 g) was slowly added over the span of about 5 minutes. The reaction was stopped after an additional 30 minutes of mixing at temperature. The product was removed from the vessel. Gamma-valerolactone was added to dissolve the polymer that was remaining in the reactor and on the impeller.
The mixture was CA 03228700 2024- 2- 12 SUBSTITUTE SHEET (RULE 26) stirred for several hours at 190 C. The gamma-valerolactone was distilled from the polymer under vacuum resulting in a solid. To perform SSP, an aliquot (30 g) of the product was ground and heated at 180 C under vacuum for 3 days on a rotary evaporator to produce the PEF
homopolymer as reported below. The polymer was then subject to solid state polymerization according to known techniques to produce the PEF homopolymer as reported below.
The PEF polymers thus produced were tested using the measurement protocols as described above and found to have the characteristics reported in Table E44 below:
