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： Residual monomer in a polymer matrix may be reduced by a method including admixing a polymer matrix comprising an amount of residual monomer and a conjugated diene. This method can be carried out under reaction conditions such that the amount of residual monomer is reduced. The monomer comprises at least one electron withdrawing substituent and the conjugated diene comprises at least one electron donating substituent. This method is particularly useful for reducing the amount of residual styrene monomer in polystyrene homopolymer and copolymer compositions.

摘要： A method of homogeneously polymerizing styrene comprising admixing an ethylenically unsaturated monomer and an initiation system that is soluble in the monomer. This system includes a metal; a peroxide, hydroperoxide or mixture thereof; and a reductant. Under appropriate reaction conditions, the cyclic oxidation and reduction of the metal produces free radicals which initiate homogeneous polymerization of the ethylenically unsaturated monomer. The invention beneficially enables relatively low temperature processing with inexpensive initiation.

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 (η0) has also been discovered.

摘要： A flame retardant brominated rubber polymeric composition, wherein the composition can include ethylene propylene ethylidene norbornene rubber polymer and from 12 weight percent to 55 weight percent of bromine covalently bonded thereto. The method can include dissolving a liquid ethylene propylene ethylidene norbornene rubber polymer in hexane with myrcene, forming the composition. The method can include dissolving ethylene propylene ethylidene norbornene rubber polymer in hexane, forming a solution, and adding bromine, or blending N-bromo-succinimide into the solution, forming a suspension. The method can include heating the suspension and stifling the suspension until all bromine in the N-bromo-succinimide has reacted with the ethylene propylene ethylidene norbornene rubber polymer, forming the composition as a solid in a liquid. The method can include removing the liquid from the solid, and flashing off the hexane from the liquid to extract the composition.
