    摘要: 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.

    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 process for the preparation of a hydroperoxide functionalized rubber compound by the conversion of triplet state oxygen to singlet state oxygen in the presence of oxygen and a light-induced photoreductant. A dispersion of an unsaturated rubber component in a carrier solvent is introduced into a reactor containing a permeable catalyst bed comprising a light-induced photoreductant component supported on a particulate substrate component and passed through the catalyst bed. A gaseous oxidizing agent is passed through the catalyst bed in contact with the rubber-containing dispersion. The catalyst bed is irradiated with electromagnetic light radiation in the ultraviolet or visible light range at an intensity sufficient to convert triplet oxygen in the oxygenated rubber component to singlet oxygen. The oxygenated rubber component is then recovered from the reactor. The reactor can comprise a tubular outer shell and a tubular inner member having a permeable wall defining an annular space containing photoreductant-supported substrate material. The oxidizing agent is introduced into the inner member and radially dispersed outward from this member into contact with the supported photoreductant. The solvent rubber component is concurrently passed into contact with the catalyst bed.
