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： 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.
摘要翻译：包含橡胶改性苯乙烯马来酸酐共聚物和聚丁烯的苯乙烯树脂组合物。该树脂通过几种方法制备，包括将聚丁烯加入到反应器中，或者将聚丁烯加入到离开反应器的浆料中，并且在进入脱挥发物之前，或者在聚合物离开脱挥发物之后，在挤出机中将聚丁烯混合到聚合物中。聚丁烯的含量为0.1至8重量％，数均分子量为900至2500.橡胶的范围为4重量％至20重量％，其粒径为0.1微米至11微米。该树脂可以挤出成片并热成型成制品，或者可以共挤出以制成层压制品，其可以是用于微波炉中加热的包装食品的容器，并且该容器具有改善的韧性，伸长率和耐热变形性属性。
