Abstract: 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.

Abstract: 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.

Abstract: A method for the production of a vinyl aromatic polymer through the use of a supported light-induced photoreductant. A reactor is provided which contains a catalyst bed comprising a light-induced photoreductant component supported on a particulate substrate forming a permeable catalyst bed. A reaction stream comprising a vinyl aromatic monomer, a soluble reductant, and a transition metal salt is introduced into the reactor and passed through the catalyst bed. In addition, a gaseous oxidizing agent is introduced into the reactor and flowed through the catalyst bed and into contact with the reaction stream. The catalyst bed is irradiated with electromagnetic radiation in the ultraviolet or visible light range at an intensity sufficient to activate the photoreductant component and produce a free radical to initiate polymerization of the vinyl aromatic monomer to form a corresponding vinyl aromatic polymer. The vinyl aromatic polymer is then recovered from the reactor. The photoreductant component is a photoreductant dye, such as a group consisting of acridine, methylene blue, rose bengal, tetraphenylporphine, A protoporphyrin, A phthalocyanine and eosin-y and erythrosin-b. The transition metal salt may be an iron, cobalt or manganese salt and the soluble reductant is selected from the group consisting of diethanolamine, thiodiethanol, triethanolamine, benzoin, ascorbic acid, ester, glyoxal trimer and toluene sulfinic acid.
