摘要： A foamed sheet containing a polymer composition including a polymer formed by polymerizing a mixture including 40% to 90% of styrenic monomers; 5% to 45% of maleate-type monomers; 0.1% to 25% by weight of elastomeric polymers with Mn greater than 6,000; and 0.1% to 10% by weight of low molecular weight polymers that include one or more monomers according to the formula CH2═CR3R2, where R3 is H or a C1-C3 alkyl group and R2 is a C1-C22 linear, branched or cyclic alkyl or alkenyl groups. The low molecular weight polymer has Mn of from 400 to 6,000 and can optionally include functional groups. The foamed sheet is made by injecting blowing agents into the polymer melt composition; mixing the blowing agent with the polymer composition; and extruding the mixture to provide a foamed sheet. The foamed sheets can be thermoformed into containers suitable for use in microwave heating of food.

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%.

摘要： High impact polystyrene (HIPS) and other impact modified styrenic polymers such as ABS and MBS tend to suffer from environmental stress cracking. On extended exposure to oily or fatty substances the plastic tends to craze, then crack and finally break. Unfortunately, a number of applications for impact modified polymers is in areas where there is a high potential to contact with oily or fatty substances. The environmental stress crack resistance (ESCR) of impact modified styrenic polymers may be increased by increasing the particle size of the impact modifier and including a low molecular weight polybutene.
摘要翻译： 高抗冲聚苯乙烯（HIPS）和其他冲击改性的苯乙烯聚合物如ABS和MBS倾向于遭受环境应力开裂。 长时间暴露于油性或脂肪物质时，塑料往往会变热，然后破裂并最后破裂。 不幸的是，冲击改性聚合物的许多应用是在与油性或脂肪物质接触的潜力很大的地区。 抗冲击改性苯乙烯类聚合物的耐环境应力开裂性（ESCR）可以通过增加抗冲改性剂的粒径并包括低分子量聚丁烯来增加。
