Description

Filed Via EFS-Web@USPTO.gov on May 23, 2024 Attorney Docket No.1001.886WO AMBIENT TEMPERATURE INITIATED, MULTISTAGE CURED POLYMERIC COMPOSITIONS Claim of Priority [0001] This application claims the benefit of the filing date of United States Provisional Application No.63/468,314, filed May 23, 2023, the contents of that application being hereby incorporated by reference herein in its entirety and for all purposes. Technical Field The present teachings relate generally to polymeric compositions suitable for forming room temperature cured products that meet performance criteria with little to no external influence. In one embodiment, the teachings are directed to an ambient temperature initiated, multistage reaction cured, high glass transition (Tg) thermoset polymer that cures without the use of any external heating mechanism. The invention is set out in the appended claims. Background [0002] Polymeric compositions often perform well at super-ambient (temperature, pressure, chemical environment) conditions. As the in-use application environment deviates more from ambient, there is a continual need for improved performance of polymeric systems. This often results in super-ambient external conditions in which the polymeric composition is reacted and cured to achieve required performance targets. For example, it is well known that heat-cured epoxy thermosets can have much higher glass transition temperatures (Tg) as well as tensile moduli and other physical properties as compared to ambient temperature cured epoxy thermosets. [0003] There is also the competing desire to minimize these external curing conditions which have economic, productivity, and environmental costs. Unfortunately, single stage acceleration of curing, starting from ambient condition, often results in both extremely short working times at ambient conditions as well as potentially uncontrolled reactions leading to deleterious product performance. [0004] Elevated glass transition polymeric compositions are one example of an improved performance target. High Tg polymeric compositions find utility in applications such as tooling boards, circuit boards, and parts for aerospace, automotive, building construction, and marine industries. High Tg compositions allow for utility under high temperature service conditions by Filed Via EFS-Web@USPTO.gov on May 23, 2024 Attorney Docket No.1001.886WO maintaining their physical properties at elevated temperatures. Other performance targets can be tensile modulus, compressive modulus, and flexural modulus, among others. [0005] As one specific example, high Tg polymeric compositions used to create tooling boards are typically made from various polymeric materials that are compounded and or mixed, then heated in an oven to temperatures that allow for high Tg compositions to be achieved. Typically, it is necessary to do this to achieve the desired glass transition temperature. These oven temperatures are often at or above the desired glass transition temperature. Additional salient properties of tooling boards can include coefficient of thermal expansion, hardness, tensile strength, flexural strength, compressive strength, strain to failure, density, and fracture toughness. [0006] High Tg polymeric compositions are commonly made from vinyl ester, acrylic, urethane, phenolic, or epoxy resins systems. Certain resin systems can provide cured products with glass transition temperatures >100 °C, which can be used in applications requiring elevated temperature performance. [0007] The existing process for making high Tg compositions involves mixing various constituents together, pouring the mixture into molds, waiting up to a day while the reaction mixture partially cures then heating the mixture in ovens for some time until full cure is achieved. Staged curing schedules are also common to avoid warping and cracking during the curing process. This process sequence can take up to a week. It requires the use of curing ovens which are a capital expense, take up valuable manufacturing space, and incur significant operating expense. As a result, the amount of product that can be produced per unit time is limited, and as such, creates a bottleneck in manufacturing. Also, these factors contribute significantly to the environmental footprint of a high Tg composition. [0008] Fundamentally, achieving high Tg polymeric compositions involves mixing and then heating curable materials at above or near the Tg that is theoretically feasible for those materials. [0009] The process of making high Tg composites also requires reactant mixtures to have a reasonable working time sufficient for mixing and dispensing into molds or trays. These molds can be very large, exceeding 100 liters in material volume with a desire for greater volumes, if possible, further emphasizing the requirement for reasonable working time. [0010] High Tg polymeric compositions should also be free of char (burnt and/or blackened material) which can be indicative of degraded properties. In the worst case, curing compositions may auto ignite. In addition, high Tg polymeric compositions should be fully cured to reduce waste and ensure consistent mechanical properties throughout their entire volume and produce long term product stability. Filed Via EFS-Web@USPTO.gov on May 23, 2024 Attorney Docket No.1001.886WO [0011] It is therefore desirable to manufacture high Tg polymeric compositions with little to no external heating. This would greatly reduce the capital required, manufacturing costs, and the environmental footprint of the produced compositions. Unfortunately, accelerating the typical curing reactions to cure at ambient condition in a single stage process typically leads to unacceptably short working times as well as potentially charred and consequently degraded compositions. [0012] As Tg represents one aspect of polymeric compositions, the present teachings overcome current constraints encountered in making high Tg compositions by providing compositions that have reasonable working times, initiate cure at or near ambient conditions and require no external heating while producing materials with a high Tg, no char, and full cure.

Detailed Description [0055] The explanations and illustrations presented herein are intended to acquaint others skilled in the art with the present teachings, its principles, and its practical application. The specific embodiments of the present teachings as set forth are not intended as being exhaustive or limiting Filed Via EFS-Web@USPTO.gov on May 23, 2024 Attorney Docket No.1001.886WO of the present teachings. The scope of the present teachings should be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference into this written description. Percentages herein refer to weight percent, unless otherwise indicated. [0056] The teachings herein are directed to a composition adapted for a multi-stage cure, such that components of the composition initiate a cure at or near ambient conditions (e.g., less than 40 °C) and proceeds to full cure with minimal external influence. The compositions herein may be such that multi-stage cure enables the manufacture of high Tg polymeric compositions. The first stage of curing creates an initial reaction exotherm by which the resulting temperature increase then activates a second stage of curing. When a sufficiently high temperature has been reached, the second stage of curing further drives the exotherm higher to produce a high Tg polymeric composition. [0057] In addition to high Tg, the multi-stage cure systems as disclosed herein may be utilized to improve a polymeric material’s strain to failure, provide higher fracture toughness, improved stiffness, improved solvent resistance, modified decomposition temperature, or any combination of those improvements. [0058] Incorporation of two or more distinct curing reactions also enables a reduction of the initial cure to less than what is necessary to cure the product fully. This assists in moderating the initial exotherm. The subsequent curing phases do not significantly participate in earlier curing phases until the necessary elevated activation temperature has been reached. The multi-stage exothermic cure mechanism approach allows for the potential of a longer working time while still allowing the system to reach full cure as the reaction occurs in multiple steps over several temperature ranges. [0059] The present teachings contemplate combining ambient temperature exothermic reaction systems with typical oven-curing exothermic reaction systems in varying amounts in which the ambient temperature system provides sufficient heat to activate the oven-curing systems without the need for an oven. The present teachings contemplate a plurality of exothermic reactions to provide an in-situ multi-stage cure commencing at or near ambient temperature. Ambient temperature reaction systems include ring opening of strained-ring groups, such as epoxy, cyclic lactone, cyclic carbonate, cyclic anhydride, dicyclopentadiene, benzoxazine, addition polymerization of vinyl ester and/or (meth)acrylate resins, and reactions involving isocyanate resins. Filed Via EFS-Web@USPTO.gov on May 23, 2024 Attorney Docket No.1001.886WO [0060] Ambient temperature-initiated ring opening of epoxy resins can occur with acidic phosphorous or sulfonic acid groups in the absence of any catalysis. Other ring opening epoxy resin reactions such as epoxy-thiol, epoxy-phenol, epoxy-hydroxy, epoxy-amine, epoxy- carboxylic acid require catalysis to provide sufficient reaction at ambient temperature. Epoxy homopolymerization is variation of epoxy-hydroxy and another exothermic reaction that can be initiated at ambient temperature with sufficient catalysis. [0061] Ambient temperature-initiated addition polymerization of vinyl ester and/or (meth)acrylate resins with peroxides in combination with suitable peroxide decomposition accelerators are well known in the art. Non-limiting examples include tertiary aromatic amines (N,N-Dimethyaniline, N,N-Dimethyl-p-toluidine, N,N-Dimethyl-o-toluidine, N,N-Diethyl-p-toluidine, N-(2- Hydroxyethyl),N-methyl-p-toluidine), transition metals, transition metal carboxylates (cobalt 2- ethylhexanoate, copper acetylacetonate, copper naphthanate), metallocenes (ferrocene), 1- Acetyl,2-phenylhydrazine, and sulfonyl chlorides (tosyl chloride, mesyl chloride, chlorosulphonated polyethylene). [0062] Cyclic carbonates react at room temperature with primary amines. [0063] Isocyanates react with active hydrogen containing materials (primary amines, secondary amines, polyols, thiols) as well as with themselves (trimerization). [0064] Oven-curing systems may incorporate ambient temperature reaction systems as well as reactions involving cyclic anhydrides and benzoxazines. Utilization of reaction systems at oven curing conditions may require different catalysts/accelerators or complete elimination of certain catalysts/accelerators. Curatives and or catalysts that physically change (melt, dissolve) at elevated temperatures or chemically change (thermally reversible reactions) can be used. For example, latent curatives, such as dicyandiamide curative in epoxy-amine reactions are possible for the elevated temperature curing reaction. Blocked isocyanates are another example of reaction systems that can be used at elevated temperatures. Latent accelerators such as ureas, known in the art of epoxy-amine reaction systems are included. Blocked catalysts, such as acid- blocked tertiary amines are also considered. [0065] The polymeric composition can also include additional ingredients in the mixture. Reinforcing components, fillers, wetting agents, rheology control agents, reinforcing fibers, thermoplastic polymers, flame retardants, pigments, and toughening agents such as core-shell particles, and foaming agents can also be part of the mixture. As potential non-limiting examples, additives can be used to alter the thermal conductivity and heat capacity of the composition; also, additives to alter the cured density (hollow particles, thermal/chemical foaming agents) are possible. Additional additives are possible to facilitate the machinability of the cured composition. Filed Via EFS-Web@USPTO.gov on May 23, 2024 Attorney Docket No.1001.886WO [0066] Thermal management fillers are useful in altering the heat capacity and thermal conductivity of the composition thereby altering the effect of the reaction exotherm. Suitable fillers for heat management include aluminum powder, boron nitride, graphite, graphene, aluminum trihydrate, iron powder, iron oxide, powdered polymers, and alumina. [0067] Suitable components for reducing density and aiding in machinability in the case of tooling boards include glass microspheres (3M K15, K20, for example). The low isotactic crush strength, typically thin walled of preferred glass microspheres enables them to break easily when being cut for instance by a CNC router. This results in quicker cutting times and less wear on CNC cutting components. Hollow particles also permit adjustment of the thermal conductivity and thermal heat capacity and provide a component that consumes volume but does not add reactive functionality can be used to modify the temperature profile. [0068] Physical blowing agents such as expandable microspheres (Expancel from Nouryon for example) may also be included to reduce the density of formed materials, although chemical blowing agents can be envisioned as well. [0069] One or more thixotropes may be included to help prevent settling of or floating of fillers in the case of formulations that cannot be agitated prior to mixing include for instance, fumed silica, Aerosil® R 208, or mixed mineral thixotropies such as Garamite 1958, or combinations thereof.

[0116] Toyal 101 is an air-atomized aluminum powder available from Toyal America. [0117] Examples 1B-H – Epoxy acidic phosphorous / epoxy – acid/anhydride system. [0118] In Example 1 the ambient temperature reaction system including epoxy and acidic phosphorous groups is combined with a typically oven cured epoxy-cyclic anhydride reaction system. Acidic phosphorous materials are selected from phosphoric acid, polyphosphoric acid, phosphonic acids, acidic phosphate esters, as well as materials with a plurality of acidic phosphorous groups. [0119] Example 1B [0120] Formulations in Example 1B demonstrate how a second reaction can be utilized to control the initial curing stage and hence provide increased open time. [0121] Formulations in Example 1B are prepared by mixing the respective A and Part Bs in a dual asymmetric centrifuge mixer (SpeedMixer® by FlackTek) speed mixer followed by mixing A and B together in a speed mixer for 15 seconds at 3500 rpm. [0122] Component amounts in the formulation are given in weight percentages in Table 1B along with the acid to epoxy stoichiometry, and whether the formulation is liquid or solid when removing Filed Via EFS-Web@USPTO.gov on May 23, 2024 Attorney Docket No.1001.886WO from the mixer. This is assessed by slightly shaking the mixture and recording the time when no movement is observed. If the resulting mixture is solid immediately after removing from the mixer it is not a viable solution as the material requires reasonable open time or working time (the time needed to maintain flow as mixed material is being dispensed). The use of an acid anhydride in the Part B such as nadic methyl anhydride (NMA) may provide longer open times at the same total acid level (as measured by acid to epoxy stoichiometry). [0123] Formulations 5, 7, 8 and 9 (shown at Table 1B) illustrate longer open times with the use of NMA at the same stoichiometry. Formulation 5 solidifies almost instantly whereas formulation 7 is still liquid after 10 minutes. The presence of NMA dilutes the phosphoric acid and does not significantly react at ambient temperature. By having at least one additional reaction, full cure is not required of the ambient temperature reaction leading to longer working times. [0124] Table 1B 5 7 9 8 Part A

[0125] Example 1C [0126] Example 1C demonstrates the effect of incorporating buffering agents into the acid curing composition as a strategy to control the peak reaction exotherm. [0127] The formulations in this example are mixed, filled into cartridges, conditioned to 55 °C and dispensed into 400ml HDPE molds. [0128] When incorporated into the curative part B, basic materials like calcium carbonate may act as buffering agents and reduce the exothermic temperature of the reaction by buffering the curative prior to mixing with the epoxy resin (part A). [0129] Component amounts in the example compositions are given as parts by weight in Table Filed Via EFS-Web@USPTO.gov on May 23, 2024 Attorney Docket No.1001.886WO 1C below, along with their associated peak temperatures.

p [0132] The formulation in Example 1D demonstrates how dual cure compositions can have sufficient open time and still generate sufficiently high temperatures needed to produce a high Tg material. [0133] The formulation shown below at Table 1D is prepared by filling parts A and B into cartridges and dispensing with static mixers into a square high density polyethylene mold. The total cartridge volume is 400 ml. The mix ratio is 4 parts epoxy part A to 1 part acid/anhydride part B. The cartridges are heated to 50 °C before dispensing. The dimensions of the resulting composite are roughly 11 cm x 9 cm x 4 cm. After dispensing the material, a thermocouple is inserted approximately in the center of the mold.

a function of time for the formulation in Table 1D. As shown in FIG 1, the exotherm from the epoxy-acidic phosphorous reaction is sufficient to heat the mixture to a point at which the epoxy-anhydride reaction starts and further increases the temperature. [0136] Example 1E [0137] Formulations in this example (see Table 1E below) are prepared as those in Example 1D. [0138] Incorporation of aluminum powder (for example Toyal grade 101), at levels of from about 5% up to about 20% by weight reduces char formation. Aluminum has a high thermal conductivity which facilitates heat transfer of the heat generated by the reaction throughout the cast object. FIG.2 visually demonstrates the reduced charring in formulation 53-14 which contains aluminum powder. Both formulations shown at Table 1E below exotherm in the center to the same temperature. The formulation without aluminum (50-2”), is soft and waxy on the edges. This is evidence of lack of cure because of insufficiently high temperatures at the edges. Without being bound by theory, some foaming is also realized for the aluminum containing formulation (43-14) presumably due to the liberation of hydrogen gas because of the reaction between aluminum, phosphoric acid, and water. [0139] FIG. 3 and FIG. 4 show graphs depicting the increase in temperature over time of Examples 50-2” and 53-14, respectively. [0140] Table 1E 50-2” 53-14

[0142] Example 1F demonstrates the effect of incorporating a catalyst into the formulation with the objective of producing a more complete cure throughout the entire object. [0143] Formulations in Example 1F are conditioned to 43 °C and dispensed from 200 ml cartridges into 400ml HDPE beakers to a height of about 5 cm. [0144] It is possible that lower temperatures at the corners of molded samples may occur because of heat losses to the environment. The temperatures at these locations may be insufficient to initiate or complete the secondary reaction. [0145] The incorporation of a phosphonium ionic liquid catalyst (Solvay Cyphos IL 169) provides a more thorough cure at the corners of molded samples. Phosphonium catalysts may reduce the activation temperature of reaction between epoxies and anhydrides. The catalyst may also increase the core peak exotherm temperature which is the temperature in the middle of the object determined by placing a thermocouple in the center after the materials has been dispensed. Table 1F shows the different core temperatures between a system with and a system without the catalyst. [0146] Component amounts in the formulations are given as weight percentages in Table 1F. [0147] An example of composites formed with and without a phosphonium ionic liquid catalyst can be seen in FIG.5. Formula 53-15A1 without catalyst is very soft at the edges of the object and uncured material can easily be removed with a spatula. Formula 53-15A4 that contains the catalyst is fully cured throughout its entire volume. [0148] Table 1F Material 53-15A1 53-15A4

[0150] Multi-functional phosphate ester curatives like those that are reaction products of phosphoric acid with epoxidized neopentyl glycol (for example Erisys GE-20) with a theoretical acid functionality of four and epoxidized trimethylolpropane (for example Erisys GE 30) with a theoretical acid functionality of six have also demonstrated the ability to increase the Tg compared to systems using a lower average functionality epoxidized phenol-based phosphate ester (for example Erisys GE 13) with a theoretical acid functionality of two. Tg was measured using a TA instruments Q 800 DMA. [0151] The formulations in Example 1G are prepared the same as those in Example 1A. Component amounts in the formulations are given as weight percentages in Table 1G. [0152] Table 1G 4_{4-1 44-2 44-3 P rt A}

[0153] Example 1H [0154] Example 1H demonstrates the benefit of incorporating foaming ability into the formulation.

Filed Via EFS-Web@USPTO.gov on May 23, 2024 Attorney Docket No.1001.886WO [0155] Low density compositions may be desirable for tooling board applications to aid in the speed and quality of machining, and for density reduction for easier handling of larger volumes. Tooling boards typically incorporate hollow glass spheres to reduce density. Expansion can also be produced by incorporation of thermoplastic expanding microspheres (for example Nouryon Expancel). Chemical blowing agents or reaction of the part B acid composition with a metal carbonate are also potential strategies for foaming, all of which may result in lower densities. [0156] Table 1H includes a formulation (sample KE) with a theoretical cured density of 1.09 g/cc but with the incorporation of expanding microspheres (Expancel 951 DU 120) to the formulation (sample JK), has a measured density of .75 g/cc as measured by hydrostatic weighing.

[0158] Example 2 (Epoxy + amine/Epoxy + latent amine) [0159] The formulations in Example 2 demonstrate another chemistry involving multistage curing Filed Via EFS-Web@USPTO.gov on May 23, 2024 Attorney Docket No.1001.886WO that can be used to drive the exotherm to a higher level than that that can be achieved by a single curative. In this example, epoxy resins are cured with a combination of ambient-temperature reactive amine and latent amine. The mixture is formulated so that the exotherm from the ambient temperature amine-epoxy reaction is sufficient to drive the composition temperature to a point at which the latent amine-epoxy reacts significantly. The exotherm from this second reaction increases the mixture temperature enabling a higher Tg composition. [0160] Formulations in Example 2 are prepared by mixing the respective epoxy (A) and amine (B) parts in a speed mixer followed by mixing A and B together in a speed mixer for 15 seconds at 3500 rpm. [0161] Component amounts in the formulation are given in weight percentages in Table 2 along with the acid to epoxy stoichiometry, the maximum exotherm, and associated Tg measured using a TA instruments Q 800 DMA. The amine (Ancamine® 1644) provides a high enough exotherm to allow the dicyanamide (Dicyanex® 1200) to continue to react. The use of both amine and dicyanamide curatives provides a higher exotherm and Tg than the use of the amine alone. [0162] Table 2 E F G

Additionally, the use of HEMA phosphate in the formulation demonstrates the use of a component that participates in more than one exothermic reaction. [0165] YDCN-500-80P is pre-dissolved in a blend of YDPN-631 and Kane Ace MX267 in the ratio described in Table 3A. One part 4-Hydroxy TEMPO is dissolved in 99 parts YDPN-631 by heating the 4-Hydroxy TEMPO past its melting point and subsequently speed mixing the heated material. The formulation as described in Table 3A is mixed under vacuum in a speed mixer. Part A, as described in Table 3A is used to fill the more voluminous side of 2:1 volumetric cartridges and Part B is used to fill the adjacent side. The two components are dispensed through a 10-24 helical static mixer at 30°C into an aluminum foil lined, 1L (10cm x 10cm x 10cm) rockwool-insulated mold and allowed to cure.

atalyze the decomposition of benzoyl peroxide at ambient temperature, initiating polymerization of the (meth)acrylate blend.4-hydroxy TEMPO is used to mediate this reaction and extend the working time. The resulting material had a peak exotherm of 229 °C, substantially higher than the decomposition temperature of the Luperox P as described in Example 3, as well as beyond the initiation temperature for epoxy-anhydride polymerization described in earlier examples. The resulting polymer did not exhibit any signs of charring due to the exotherm. Said composite material had an Onset Tg of 162 °C and Tan Dela Tg of 201 °C. [0173] Example 5 – Epoxy homopolymerization / epoxy-anhydride [0174] In Example 5, a high Tg composition arises from sufficient catalysis of epoxy homopolymerization to slowly increase the temperature to a point where epoxy-anhydride reaction occurs.

[0177] The material temperature ramp up is measured with a probe in the core of the board. The first reaction temperature ramp up is approximately 0.08 °C/min, the subsequent reaction has an onset temperature at 65 °C, ramp up of 11.4 °C/min. The maximum temperature recorded was 178 °C.
