摘要： A method of preparing a polystyrene blend that includes combining a first polystyrene composition having a first melt flow index with a second polystyrene composition having a second melt flow index and forming a polystyrene blend, the second melt flow index being at least 2 dg/min higher that the first melt flow index. The polystyrene blend has an observed tensile strength value greater than 3% above the expected tensile strength value. The second polystyrene composition can include a recycled polystyrene material, which can include expanded polystyrene. An alternate method of preparing the polystyrene blend includes combining a polystyrene composition with a styrene monomer to form a reaction mixture, polymerizing the reaction mixture and obtaining a polystyrene blend, where the polystyrene containing composition has a melt flow index at least 2 dg/min higher than the melt flow index of the styrene monomer after it has been polymerized.

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： It has been discovered that improved polystyrene products may be obtained by polymerizing styrene in the presence of at least one multifunctional initiator, at least one chain transfer agent, and at least one cross-linking agent. The presence of the multifunctional initiator tends to cause more branched structures in the polystyrene. A mathematical model that helps optimize the levels of these additives for given molecular weights, melt flow indices (MFIs) and zero shear viscosities (eta0) has also been discovered.
