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.

With respect to the selection of thermoplastic resin, EP 3,231,836 acknowledges that while there has been interest in thermoplastic resins, in particularly polyester-based resins, this interest has encountered difficulty in development, including difficulty in identifying suitable foaming grades of such resins. Moreover, while EP 3,231,836 notes that certain polyethylene terephthalate (PET) resins, including recycled versions of PET, can be melt-extruded with a suitable physical and/or chemical blowing agent to yield closed-cell foams with the potential for low density and good mechanical properties, it is not disclosed that any such resins are at once are able to produce foams with good environmental properties and good performance properties, and are also able to be formed from sustainable sources. The '836 application identifies several possible polyester resins to be used in the formation of open-celled foams, including polyethylene terephthalate, poly butylene terephthalate, poly cyclohexane terephthalate, polyethylene naphthalate, polyethylene furanoate or a mixture of two or more of these. 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 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) (PEF) using ethylene glycol and 2,5-furandicarboxylic acid is mentioned but is not exemplified. Essentially amorphous (i.e., no crystallinity as per 0 JIG 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. VVhile 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.

3 SUMMARY
As described above, a continuing need exists for polymeric materials, and particularly polymeric foams, that are sustainable and environmentally friendly, and simultaneously a continuing need exists for such polymeric foams that at once are able to provide low density and high strength.

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,"
Firas Awaja, Fugen Daver, Edward Kosior, 16 August 2004, available at htta511AlgiSMOSURQap_TI22155, which is incorporated herein by reference. 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 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.

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 comprising 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 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 ¨ TPP6, 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 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-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.

The present invention includes the advantages formation of PEF foams having a high volume percentage of closed cells over a range of relative foam densities (RFDs) and using a range of blowing agents. 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 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 (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 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") (measure 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 0297) = 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 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 - 3 - PEF FOAM PREPARATION USING PEX1 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 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 foam thus produced were observed to be good, high quality foam, and were then tested and found to have the properties reported in Table E2 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 ASTM C297 and compressive properties were determined based on ASTM C365 and ASTM D1621/1S0 844.
As can be seen from the results reported in Table E2 the use of 1336mzz(E) blowing agent, with a PEF polymer that had no tannin moieties present, produced a foam that had a dramatically and unexpectedly improved density compared to the foam made with CO2, that is, the density of the foam produced with 1336mzz(E) resulted in density value that is about 2 times less than (about half of) the density of the CO2 blown foam. Furthermore the use of the trans1336mzz(E) also unexpectedly produced a foam that was dramatically superior to even the other HFO blowing agent foams tested in this example in terms of both tensile and compressive strength. For example, the foam blown with trans1336mzz(E) had about a 2.5 times better tensile strength and about a 5 times better compressive strength than the 1233zd foam.
Example 4- PEF FOAM PREPARATION USING PEX1 AND trans-1336mzz as BLOWING AGENT
Comparative Example 1 was repeated, except: (1) the CO2 blowing agent was replaced, on a molar equivalent basis with trans-1336ze; and (2) the pre-foaming pressure was decreased to 170 psig. The foam thus produced was observed to be a good, high quality foam, and was then tested and found to have the properties as reported in Table E4 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):

Furthermore the use of the trans1336mzz(E) also unexpectedly produced a foam that was superior to the other HFO

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 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 10- 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, on a molar equivalent basis, with tran51336mmzz; and (ii) in two separate runs the process conditions were modified in a manner to produce a foam blowing agent in the cells that was within 15% of the moles in 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 foam produced was tested to determine various properties, including strength and modulus properties, and was found to be dramatically superior to the foam made with HFC-134a in each of the measured property, as reported in Table El 0 below:
TABLE El0 Ex Blowing RFD Avg. RELATIVE MECHANICAL PROPERTIES*

As can be seen from TABLE El 0 above, on a molar equivalent of blowing agent in the foam (i.e., withing 15%), the foams made using cis1336mzz 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.

Comparative Example 3 was repeated, except: (i) the isopentane blowing agent was replaced in the process with trans1336mmzz(E) on a molar equivalent basis; and (ii) in two separate runs the process conditions were modified in a manner to produce a foam having moles of blowing agent within 30% of the moles of blowing agent in the foam in Comparative Example 3. In particular, the foams thus produced using trans1336mzz(E) according to this Example were observed to be acceptable foams and had RFD values that were within about 15% of the RFD produced using isopentane in Comparative Example 3. The foam produced was tested to determine various properties, including strength and modulus properties, and was found to be dramatically superior in each of the measured property, as reported in Table Ell 12 below:

As can be seen from TABLE Ell-12 above, the foams made using trans1336mzz were surprisingly and dramatically superior to the foam made using isopentane in terms of all physical strength and modulus properties tested, except one. For example, the foam made with trans1336mzz produced a foam with both tensile and compressive moduli that were more than 7 times better than the modulus of foam made with isopentane, while at the same time having compressive and tensile strength properties that were at least 20% better than foam made using isopentane, with only one exception_ This result shows that dramatic and unexpected improvement in physical properties of the foam can be achieved according to the present invention.
Example 13¨ PEF PREPARATION AT MW ABOUT 33,000 WITH PMDA CHAIN
EXTENDER AND SSP
A bio-based polyethylene furanoate homopolymer was prepared by esterification and polycondensation of 2,5-furandicarboxylic acid with mono ethylene glycol according to known methods to produce PEF homopolymer, which is then treated according to known techniques with the chain extender PM DA at 0.7% by weight and then subject to solid state polymerization according to known techniques to produce a PEF homopolymer. The PEF polymer was tested and found to have the following characteristics, using the same measurement techniques as described in Example 1:
Molecular Weight ¨ .=33,000 Glass Transition Temperature ¨ 90.5 C
Melt Temperature - 224 C
Decomposition Temperature ¨ 341 C
Crystallinity - 45%

The PEF polymer so produced is referred to in these Examples as PEX13.
Comparative Example 4¨ PEF FOAM PREPARATION USING PEX13 AND CO2 AS
BLOWING AGENT
1 gram of PEX13 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 14- 16 PEF FOAM PREPARATION USING PEX31 AND trans1336mzze as BLOWING AGENT
Comparative Example 4 was repeated, except the CO2 blowing agent was replaced in the process with trans1336mzz(E) in three separate runs. The foam thus produced using trans1336mzz(E) 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 4. The foam produced was tested to determine various properties, including strength and modulus properties, and was found to be dramatically superior in each of the measured properties, as reported in Table E14-16 below:

This result is unexpected.
Also, the foam made with trans1336mzz(E) produced foams with both tensile and compressive modulus that is at least 1.2 times the value produced using CO2. This result is unexpected.
