    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: 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 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.
