摘要： A styrene copolymer composition comprising at least one alkyl acrylate and/or at least one alkyl methacrylate wherein the styrene copolymer composition has a bimodal molecular weight distribution. A method of producing a styrene copolymer comprising reacting styrene and at least one alkyl acrylate and/or at least one alkyl methacrylate, wherein the alkyl acrylate comprises an alkyl group having from 8 to 12 carbon atoms and the alkyl methacrylate comprises an alkyl group having equal to or greater than 10 carbon atoms. A method of increasing the molecular weight distribution in a styrene copolymer comprising incorporating at least one alkyl acrylate and/or at least one alkyl methacrylate wherein the styrene copolymer has a polydispersity index equal to or greater than 3.

摘要： Peroxide initiators are disclosed that can be used at lower temperatures during HIPS production. Enhanced formation of graft polymers between polystyrene and polybutadiene (rubber) can be accomplished by using these lower temperature peroxide initiators that have a 1 hour half-life period at one or more temperatures from 95° C. to less than 111° C. during the pre-inversion stage. “Higher” temperature initiators are used during and/or after inversion. The use of such “low” temperature initiators improves polymerization rates and grafting values, while reducing the swell index and the amount of rubber used, thereby producing improved HIPS more rapidly and at a lower cost. Also disclosed are HIPS compositions and products produced by such “low” temperature initiators as well as a method of producing improved HIPS.
摘要翻译：公开了可以在HIPS生产期间在较低温度下使用的过氧化物引发剂。在聚苯乙烯和聚丁二烯（橡胶）之间增强的接枝聚合物的形成可以通过使用这些低温过氧化物引发剂来实现，该引发剂在一个或多个温度从95℃到小于111℃的时间内具有1小时的半衰期预转换阶段。在反转期间和/或之后使用“较高”的温度引发剂。使用这种“低”温度引发剂提高了聚合速率和接枝值，同时降低了溶胀指数和使用的橡胶的量，从而以更低的成本更快速地生产改进的HIPS。还公开了由这种“低”温度引发剂生产的HIPS组合物和产物以及生产改进的HIPS的方法。
