摘要： A polymer blend composition having improved physical properties comprises (i) 70% to 95% by weight of a blend of a styrene maleic anhydride (SMA) copolymer, e.g., rubber modified styrene maleic anhydride copolymer and a styrene polymer e.g., polystyrene or high impact polystyrene (HIPS) and (ii) from 30% to 5% by weight of an acrylic copolymer, e.g., a rubber modified styrene methyl methacrylate (SMMA) copolymer which acts as a compatibilizer for the SMA copolymer, which may be a regrind, and the styrene polymer. This polymer blend composition has good impact strength and elongation properties. The weight percent ratio of the SMA copolymer to styrene polymer in component (i) may be 95:5 or 5:95 based on the total weight of component (i). The polymer blend composition may be extruded into sheet and thermoformed into an article, e.g., a container for packaged foods or may be co-extruded to produce a laminated article.

摘要： Styrenic resin composition comprising a rubber modified styrene maleic anhydride copolymer and polybutene. The resin is prepared by several methods including adding polybutene into the reactor, or adding polybutene to the syrup exiting the reactor and prior to entering the devolatilizer, or compounding polybutene into the polymer in an extruder after the polymer exits the devolatilizer. The polybutene ranges from 0.1 to 8% by weight and has a number average molecular weight from 900 to 2500. The rubber ranges from 4% to 20% by weight and has a particle size from 0.1 micron to 11 microns. The resin can be extruded into sheet and thermoformed into an article or can be coextruded to produce a laminated article, which may be a container for packaged foods that can be heated in microwave ovens and which container has improved toughness, elongation, and heat distortion resistance properties.

摘要： Packaging material comprised of a multilayer thermoplastic film structure may be used to form packaging articles, for example, stand up pouches, laminating films, and sealing/lidding stocks. The multilayer film structure contains a first layer comprised of an improved rubber modified styrenic copolymer, i.e. rubber modified styrene methyl methacrylate, a second layer comprised of a moisture barrier material, e.g. polyethylene, and a tie layer between the first and second layers made of a material selected from the group consisting of a styrene butadiene block copolymer, an ethylene vinyl acetate resin, and a maleic hydride modified ethylene vinyl acetate. An inner layer or layers of material having oxygen barrier properties, mechanical enhancement properties, or adhesive properties and a second tie layer comprising an appropriate material may be co-extruded with the first and second layers, and the tie layers for desired properties of the packaging material.The improved rubber modified styrenic copolymer of the first layer includes a continuous phase and a dispersed phase, where A) the continuous phase contains a polymer composition resulting from the polymerization of a monomer mixture containing a styrenic monomer and an alkyl (meth)acrylate monomer in the presence of the dispersed phase; and B) the dispersed phase contains one or more block copolymer selected from diblock and triblock copolymers of styrene-butadiene, styrene-butadiene-styrene, styrene-isoprene, styrene-isoprene-styrene, partially hydrogenated styrene-isoprene-styrene. The multilayer film structure generally is relatively clear to transparent with a Haze value ranging between 0.1% and 40%, and most preferably about 10%.

摘要： A thermoplastic sheet that includes a continuous phase and a dispersed phase, where A) the continuous phase contains a polymer composition resulting from the polymerization of a monomer mixture containing a styrenic monomer and an alkyl (meth)acrylate monomer in the presence of the dispersed phase; and B) the dispersed phase contains one or more block copolymer selected from diblock and triblock copolymers of styrene-butadiene, styrene-butadiene-styrene, styrene-isoprene, styrene-isoprene-styrene, partially hydrogenated styrene-isoprene-styrene. The thermoplastic sheet is formed by extruding a thermoplastic composition that is cut to desired dimensions to form thermoplastic items, e.g. identification cards, credit cards, bank cards, key cards, gift cards, phone cards, playing cards, menus, and the like. Indicia and/or printing can be applied to the items to provide for commercial applications. The sheet may be opaque or may be relatively clear to transparent with a Haze value of 0.01% up to 10%.
