Description

1 / 32 Transparent polypropylene polymer composition for thermoforming, and method for forming a thermoformed product. CROSS-REFERENCE TO RELATED REQUESTS

[001] This application claims the benefit of Provisional Patent Application No. US 63 / 046,491, filed June 30, 2020, which is incorporated herein by reference in its entirety for all purposes. BACKGROUND OF THE INVENTION A - Field of Invention

[002] The present invention relates generally to polymeric compositions containing polypropylene that can retain clarity after being subjected to multiple rounds of extrusion. B - Description of the Related Technique

[003] Polypropylene has been used in multiple industries. For example, compositions containing polypropylene are used in packaging for consumer products, plastic parts for various industries, including electrical, equipment manufacturing and automotive industries, household appliances, special devices such as hinges, and textiles. In some applications, such as food storage containers, cups, lids, etc., good clarity of the product resulting from the manufacture of polypropylene is desired.

[004] One of the problems associated with the manufacture of products based on polypropylene composition can be waste and / or loss of clarity. For example, a typical manufacturing process for such products includes the thermoforming of an extruded polypropylene sheet within a tool to form a thermoformed product. Typically, after the thermoforming process, part(s) of the extruded sheet is / are sold, while other portions, portions not removed, may be recycled and extruded again to Petition 870260068251, dated 10 / 07 / 2026, page 5 / 85 2 / 32 forming additional extruded sheets in order to avoid waste. Unfortunately, however, the recycled portions typically lose clarity due to the extrusion process, which usually introduces energy in the form of heat and / or pressure. This energy can result in lower clarity of the recycled portions when compared to the clarity of the originally produced extruded sheet. One way to deal with this loss of clarity is not to use recycled materials, especially in cases where high clarity is desired for the article being manufactured. Stated clearly, the loss of clarity from multiple extrusion passes can result in waste, which can increase production costs. US Patent 10,414,086 provides a discussion of how multiple extrusion passes for a given polymer resin can affect the resin's properties. SUMMARY OF THE INVENTION

[005] An observation has been made that provides a solution to at least some of the aforementioned problems. In one aspect, the solution may involve providing a composition with a polypropylene copolymer in combination with particular amounts of an arylamide containing a clarifying agent and / or a phosphate ester salt containing a clarifying agent. It has been found that this combination can provide polypropylene-based compositions with relatively low initial haze and minimal to no increase in haze after multiple extrusion passes. Therefore, the compositions of the present invention can be recycled without compromising the haze value of the resulting thermoformed article made with the recycled material. In comparison, when the polypropylene copolymer is combined with other clarifying agents (e.g., a sorbitol-containing clarifying agent), a substantial increase in haze may occur after multiple extrusion passes.As illustrated, in a non-limiting way, by the examples in this article. Petition 870260068251, dated 10 / 07 / 2026, p. 6 / 85 3 / 32 dido, the polymeric compositions of the present invention containing at least 95% by weight of a polypropylene copolymer and 50 ppm to 2000 ppm of an arylamide containing a clarifying agent and / or a phosphate ester salt containing a clarifying agent may have a haze value of A after being extruded once and a haze value of B after being extruded 5 times, wherein the ratio of A to B is 1 to 1.35. The haze values ​​for A and B can be determined by ASTM D1003 (by HazeGard) with a thickness of about 1.02 mm (40 mil). An advantage of the present invention is that portions of material removed from an extruded polypropylene sheet that is thermoformed into a manufactured product can be recycled and extruded again to form another extruded sheet or film with minimal or no loss of clarity from the extruded sheet that has the recycled material.In other words, polymer composites can be safely recycled without compromising clarity, which can help increase the cost efficiency of the production process.

DETAILED DESCRIPTION OF THE INVENTION

[023] A finding has been made that provides a solution to at least some of the aforementioned problems associated with polypropylene compositions used for thermoforming. In one aspect, the invention may include a polymeric composition containing Petition 870260068251, dated 10 / 07 / 2026, p. 14 / 85 11 / 32 at least 95% by weight of a polypropylene copolymer and 50 ppm to 2,000 ppm of an arylamide-containing clarifying agent or a phosphate ester salt containing a clarifying agent or a combination thereof. As illustrated in the non-limiting examples, the polypropylene-containing polymer compositions of the present invention have low haze values ​​and show relatively less haze buildup even after multiple extrusion passes. This can increase the recyclability of the compositions of the present invention, which can help reduce the waste normally associated with thermoforming processes.

[024] These and other non-limiting aspects of the present invention are discussed in more detail in the following sections. A. Polymer composition

[025] The polymeric composition of the present invention may contain, i) at least 95% by weight, such as 95% by weight to 99.9% by weight or at least any one of, equal to any one of, or between any two of 95, 96, 97, 98, 99, 99.1, 99.2, 99.3, 99.4, 99.5, 99.6, 99.7, 99.8, and 99.9% by weight of polypropylene copolymer and ii) 50 ppm to 2000 ppm or at least any one of, equal to any one of, or between any two of 50, 100, 200, 300, 400, 500, 600, 800, 1000, 1200, 1400, 1600, 1800 and 2000 ppm of aryl starch containing a clarifying agent or phosphate ester salt containing a clarifying agent or a combination thereof.In some aspects, the polymeric composition of the present invention may contain at least 95% by weight, such as 95% by weight to 99.9% by weight, or 96% by weight to 99.9% by weight, or 97% by weight to 99.9% by weight, or 98% by weight to 99.9% by weight, or 99% by weight to 99.9% by weight, of polypropylene copolymer and 50 ppm to 400 ppm or 100 ppm to 300 ppm of aryl starch containing a clarifying agent.

In some respects, the polypropylene copolymer, such as the propylene-ethylene random copolymer, may have a soluble xylene content of less than 8% by weight, such as 1% by weight to 4% by weight, or at least any one in between, equal to any one in between, or between any two of 1, 2, 3 and 4% by weight.In some respects, polypropylene copolymer, such as propylene-ethylene random copolymer, can have a polydispersity (Mw / Mn) of 3 to 15 or at least any one in between, equal to any one in between, or between any two of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15, where polydispersity is measured by gel permeation chromatography (GPC). In some respects, polypropylene copolymer such as propylene-ethylene random copolymer may have a melt flow rate (MFR) of 0.1 g / 10 min to 150 g / 10 min, or 1 to about 60 g / 10 min, or 1 to about 30 g / 10 min, or 1 to about 10 g / 10 min, or to about 7 g / 10 min, or at least any one of these, equal to any one of these, or between any two of 0.1, 1, 2, 3, 4, 5, 6, 7, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140. 150 and 160 g / 10 min at 230 °C, 2.16 kg measured according to ASTM D-1238.

In Petition 870260068251, dated 10 / 07 / 2026, p. 17 / 85 14 / 32 In some aspects, polypropylene copolymer, such as propylene-ethylene random copolymer, may have a combination of, or all of, the properties mentioned here.

[028] Polypropylene copolymer can be prepared through conventional polymerization processes, such as those known in the art. Examples of such polymerization processes include abrasive slurry, liquid bulk, and gas-phase polymerizations. In abrasive slurry polymerization processes, polymerization occurs in the presence of a solvent, for example, hexane, within a closed-circuit reactor or a continuous stirred tank. Polymerization can also be carried out by bulk polymerization, where liquid propylene and ethylene serve as both monomer and diluent. In a typical bulk process, one or more closed-circuit reactors are usually used. In other respects, the copolymer can be produced by gas-phase polymerization of propylene and ethylene, which is normally carried out in a fluidized bed reactor.The polymer fluff or powder produced from the polymerization reaction can be removed from the reactor and then processed using conventional techniques, such as extrusion, to produce the desired copolymer pellets. The amount of ethylene monomer used during the copolymer polymerization is desirably proportional to the desired final ethylene content of the target propylene copolymer. In some embodiments, the ethylene content during polymerization can vary from 0.1 to 5% by weight, or 0.1 to about 3% by weight, or 0.1 to about 2% by weight, based on the total weight of the monomers, e.g., ethylene and propylene, present during polymerization. In some aspects, the polypropylene copolymer, such as the propylene-ethylene random copolymer, can be prepared using metallocene catalysts or Ziegler-Natta catalyst. Petition 870260068251, dated 10 / 07 / 2026, page 18 / 85 15 / 32

[029] Ziegler-Natta catalysts, which are well known in the art and useful in the preparation of isotactic polypropylene, can be derived from a halide of a transition metal, such as titanium, chromium, or vanadium, with a metal and / or alkyl hydride, typically an organoaluminum compound, as a co-catalyst. In some aspects, the catalyst may contain a titanium halide supported on a magnesium compound. Ziegler-Natta catalysts, such as titanium tetrachloride (TiCl4) supported on an active magnesium dihalide, such as magnesium dichloride or magnesium dibromide, as described, for example, in US Pat. Nos. 4,298,718 and 4,544,717, both to Mayr and others, and which are incorporated herein by reference, are supported catalysts. Silica can also be used as a support.The supported catalyst can be used in conjunction with a co-catalyst or electron donor, such as an alkylaluminum compound, for example, triethylaluminum (TEAL), trimethylaluminum (TMA), and triisobutylaluminum (TIBAL). Clarifying agent

[030] The polymeric composition of the present invention includes a phosphate ester salt containing a clarifying agent and / or an aryl starch containing a clarifying agent.

[031] Non-limiting examples of phosphate ester salts containing a clarifying agent include 2,2-methylene-bis(4,6-di-tert-butylphenyl)phosphate, and / or aluminum hydroxybis(2,4,8,10-tetrakis(1,1-dimethyl) 6-hydroxy-12Hdibenzo[d,g][1,2,3][dioxaphocin 6-oxidate].

In some aspects, the polymer composition may have a toothed Izod impact strength greater than 0.9 ft-lb / in, such as 1 ft-lb / in to 1.5 ft-lb / in at 23°C, as measured according to D638. In some aspects, the polymer composition may have a tensile modulus greater than 210 Kpsi, such as 211 KPsi to 300 KPsi at 23°C, as measured according to D 638. In some aspects, the polymer composition may have an elongation at break greater than 180%, such as 200% to 250% at 23°C, as measured according to D-638.In some respects, the polymer composition may have a crystallization temperature of approximately 100°C to 135°C, or 115°C to 130°C, or 120°C to 125°C, as determined by differential scanning calorimetry (DSC) according to ASTM D-3418D.

[039] In some aspects, before any extrusion of the polymer composition in an extruder, the polymer composition may exhibit a no-yellowing index (YI) of less than 1, or -5 to 0, or -3 to -1.5, or -2.7 to -2, as measured in accordance with ASTM D-6290. In certain embodiments, after 1, 2, 3, 4, or 5 extrusions of the composition Petition 870260068251, dated 10 / 07 / 2026, page 22 / 85 19 / 32 polymeric composition through a slit or die of an extruder at a temperature of about 285°C (545°F), the YI may increase. For example, and without limitation, after 1, 2, 3, 4, or 5 extrusions of the polymeric composition through a slit or die of an extruder at a temperature of about 285°C (545°F), the YI may vary from -2 to 2.5, or -1.8 to 2, as measured according to ASTM D-6290. In some aspects, the polymeric composition may exhibit a Color L of 60 to 85, 70 to 80, 72 to 78, or about 74, as measured according to ASTM D-6290. In some aspects, the polymer composition may exhibit a Color a less than 1, less than 0, -2 to 0, -1 to 0, or -0.7 to -0.2, as measured in accordance with ASTM D-6290.

[041] In some respects, the polymeric composition may have a combination of all the properties mentioned here, or it may have all of them. C - Methods for making polymeric compositions and thermoforming methods

[042] The polymeric composition of the present invention can be made by various methods known in the art, such as extrusion, injection molding, thermoforming or similar methods. For example, the components, such as polypropylene copolymer, arylamide containing a clarifying agent, and / or phosphate ester salt containing a clarifying agent, and one or more additives can be mixed as a dry mix and then melted as extrudates to form the polymeric composition. The extruder used can be any type of extruder known in the art. Extrusion can be carried out at a temperature high enough to melt the composition, but as low as possible to avoid excessive thermal degradation of the components. In certain aspects, the thermoplastic composition can be subjected to multiple sequential passes through an extruder.Without being limited by theory, it is believed that subjecting a polymer resin to one or more passes through an extruder simulates the accelerated aging of the polymer resin due to the high pressures and temperatures encountered by the polymer resin during extrusion. Furthermore, without being limited by theory, it is believed that subjecting a polymer resin to passes through an extruder simulates the reprocessing of the polymer coating in extruded sheet thermoforming. In each pass, the thermoplastic composition can be extruded through a slit or die. The extruded material can be cooled, if desired. For each extrusion, the final melt temperature before extrusion through a die can independently be from 302 to about 600°F (150–315°C), with pressure. Petition 870260068251, dated 10 / 07 / 2026, page 24 / 85 21 / 32 independently varying from about 100 to about 30,000 psi (0.7-207 mPa).

[043] One aspect relates to a method of forming a thermoformed product containing the polymeric composition. The method may include extruding the components, such as polypropylene copolymer, arylamide containing a clarifying agent and / or phosphate ester salt containing a clarifying agent, and one or more additives to form a starter product, and thermoforming the starter product to form a thermoformed product. The starter product may be an extruded sheet or a film containing the polymeric composition. Thermoforming the starter product may include subjecting the starter product to heat, vacuum or pressure, or combinations thereof to convert the starter product into a thermoformed product. For example, and without limitation, the starter product may be thermoformed by placing the starter product in a portiotool.The initial product within the tool can be subjected to heat, vacuum, or pressure, or combinations thereof, causing the initial product to conform to the shape of the tool's interior walls. In some cases, the initial product can be heated before being placed inside the tool. The heated initial product can then be placed inside the tool, the tool can be closed over the initial product, and a vacuum or pressure can then be applied to the tool. Applying vacuum or pressure to the heated initial product inside the tool causes the initial product to conform to the shape of the tool's interior, thus forming the thermoformed article. The thermoformed product formed in the desired shape can be removed from the tool. The unremoved portion of the initial product, for example, the sheet web and / or the non-thermoformed residue portion of the sheet, can be reground, reused, and / or recycled to make a second initial product.The second initial product can be thermoformed to form another thermoformed product. The second... Petition 870260068251, dated 10 / 07 / 2026, page 25 / 85 22 / 32 The initial product and the other thermoformed product may have haze values ​​that are comparable to the initial product and the first thermoformed form. In other words, the polymer composition of the present invention and / or products containing the polymer composition have stable haze values ​​even after being subjected to 2, 3, 4, 5 or more extrusion passes, which allows articles containing the polymer composition to be recycled without loss of clarity for the recycled portions or manufactured products made from at least a portion of the recycled portions.

[044] In some respects, the initial product may be formed by extruding the molten polymer composition through a groove or die and cooling, for example, cooling the extrudate to form the initial product, for example, the extruded sheet. The extrusion of the molten polymer composition may occur at a temperature ranging from 150°C to 315°C or at least any one, equal to any one, or between two of 150°C, 160°C, 170°C, 180°C, 190°C, 200°C, 210°C, 220°C, 230°C, 240°C, 250°C, 260°C, 270°C, 280°C, 290°C, 300°C, 310°C, and 315°C. In some respects, the extruded sheet may have a thickness of 0.5 to 100 mm, 12 to 20 mm, 12 to 16 mm, or 16 to 20 mm, or at least any one in between, equal to any one in between, or between any two of 0.5, 1, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 30, 40, 50, 60, 70, 80, 90, and 100 mm.In some respects, the initial product may be a multi-layer extruded sheet, and each layer of the multi-layer extruded sheet may independently have a thickness of 0.5 to 100 mm, 12 to 20 mm, 12 to 16 mm, or 16 to 20 mm, or at least any one in between, equal to any one in between, or between any two of 0.5, 1, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 30, 40, 50, 60, 70, 80, 90, and 100 mm. In some respects, the initial product may be a molded sheet or an oriented sheet. Petition 870260068251, dated 10 / 07 / 2026, p. 26 / 85 23 / 32

[045] In some respects, the thermoforming of the initial product subjects the initial article to solid-state elongation. In some respects, the extruded sheet may be reheated and thermoformed within a tool. During the shaping of the extruded sheet to the shape of the tool interior, the extruded sheet may undergo solid-state stretching in one or more directions, thus forming a stretched solid-state thermoformed product from the extruded sheet. D - Products containing polymeric compositions

[046] The polymeric compositions of the present invention can be comprised in a manufactured product. The manufactured product can be an extruded, blow-molded, injection-molded, and / or thermoformed product. In some aspects, the manufactured product can be transparent.

[047] Examples of manufactured product include household products, food storage containers, kitchen utensils, plates, cups, measuring cups, drinking glasses, strainers, turkey basters, non-food storage containers, filing cabinets and particularly clear drawers used in such cabinets, general storage devices such as organizers, bags, welder boxes, films, coatings and fibers, sacks, adhesives, yarns, fabrics, bottles, jars, plates and cups, claws and the like. The manufactured product may be rigid packaging such as deli containers and lids, including those used for sauces, pasta salad dressings, dairy containers and lids, including those used for storing cottage cheese, butter and yogurt, personal hygiene products, and bottles and jars.In these and other uses, resins can be combined with other materials, such as particulate materials, including talc, calcium carbonate, wood, and fibers, such as glass or graphite fibers, to form matte.

[050] Compositions C-1 to C-6 have similar stiffness and Izod impact strength. The crystallization temperature (Tc) of the compositions is consistent with their nucleating agent / clarifying agent content. Compositions C-4 and C-5 of the invention exhibit impressive haze values ​​while using a much smaller amount of clarifying agent, (1,3,5-tris(2,2-dimethylpropanamido)benzene and 2,2'-methylenebis(4,6-di-tert-butylphenyl)phosphate, respectively). The haze values ​​of all samples increased after autoclaving at 130 °C for 30 minutes. Composition C-5 shows the lowest post / pre-haze ratio. FIG. 1 shows the percentage increase in haze after autoclaving of compositions C-1 to C-6.

[051] The properties of the invention compositions C-4 and C-5 were studied for multi-pass extrusion. The extrusion conditions used for C-4 and C-5 are given in Tables 4 and 5, respectively.

[052] The melt flow rate (MFR) and yellowness index (YI) of the compositions increased after each pass. For composition C-5, the increase in haze value with multiple extrusion passes was moderate, but for composition C-4 the haze value remained almost the same, around 15%, even after 5 extrusion passes. Of all compositions of the invention, C4 and C5 exhibit excellent low haze values, and composition C4 shows a minimal change in haze values ​​with multiple grinding and extrusions.
