摘要： It has been discovered that improved polystyrene products may be obtained by polymerizing styrene in the presence of p-t-butyl styrene (TBS) and optionally at least one di-olefinic substituted aromatic compound, such as isopropenyl styrene, sec-butenyl styrene, m-isobutenyl styrene, p-diisopropenyl benzene, diallyl benzene, and/or diallyl phthalate. The resulting copolymers have a higher glass transition temperature (Tg), a higher molecular weight distribution (MWD), a higher Mz, and a lower melt flow index (MFI) as compared with a polymerized product made by an otherwise identical method except that TBS and/or the di-olefinic substituted aromatic compound are not used. These copolymers are also more highly branched as compared with a polymerized product made by an otherwise identical method in the absence of TBS and/or a di-olefinic substituted aromatic compound.

摘要： It has been discovered that improved polystyrene products, such as high impact polystyrene (HIPS), may be obtained by polymerizing styrene with a diene polymer in the presence of at least one multifunctional initiator. The presence of the multifunctional initiator tends to cause more branched structures in the polystyrene. Unexpectedly, the ratio of % gel to % rubber (G/R or rubber phase volume) increases as the swell index increases which is the opposite of the conventional trend. Additionally, acceptable G/R values can be achieved at increased polymerization rates with these initiators.
摘要翻译：已经发现，通过在至少一种多官能引发剂的存在下，用二烯聚合物聚合苯乙烯可以获得改进的聚苯乙烯产物，例如高抗冲聚苯乙烯（HIPS）。多官能引发剂的存在倾向于在聚苯乙烯中引起更多的支化结构。出乎意料的是，凝胶％与橡胶比（G / R或橡胶相体积）的比例随着膨胀指数的增加而增加，这与传统趋势相反。另外，用这些引发剂可以在增加的聚合速率下实现可接受的G / R值。

摘要： A styrenic composition including a polar modified styrenic co-polymer resulting from the polymerization of a combined mixture of at least one styrenic monomer and at least one comonomer and a biodegradable component is disclosed. The at least one comonomer includes a polar functional group and the polar modified styrenic co-polymer and the biodegradable component are combined to obtain a styrenic composition having a biodegradable component. Also disclosed is a method of enhancing bio-polymer miscibility in a styrenic based polymer. The polarity of a blend is manipulated by combining a styrenic monomer and a polar co-monomer to form a combined mixture and subjecting the combined mixture to polymerization to obtain a styrenic polymer blend to which a bio-polymer is added.

摘要： It has been discovered that improved polystyrene products may be obtained by polymerizing styrene in the presence of at least one multifunctional initiator that is trifunctional or tetrafunctional and at least one lower functionality initiator that is difunctional or monofunctional. These polymers may have increased Mz, increased MFI, and increased MWD. Optionally the resin may include at least one chain transfer agent, at least one cross-linking agent and/or a styrene-conjugated diene-styrene block copolymer. The presence of the multifunctional initiator tends to cause more branched structures in the polystyrene.

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。
