Abstract

Impact resistant graft polymeric materials are made by polymerizing 97 to 70 parts by weight of styrene, or a mixture of styrene and acrylonitrile in a weight ratio of from 90:10 to 65:35, in the presence of 3 to 30 parts by weight of a copolymer of 30 to 90 parts by weight of butadiene and 10 to 70 parts by weight of a C3-C18 alcohol ester of an unsaturated carboxylic acid, the copolymer having a K value of between 50 and 150. Specified carboxylic esters are n-butyl and 2-ethylhexyl acrylates, di-n-butyl and diisobutyl fumarates, and di-n-propyl maleate. The styrene-containing monomeric material may contain minor amounts of other monomers, e.g. alpha-methyl styrene, vinyl toluene or chlorostyrene. In addition to the carboxylic esters of the defined type, the butadiene copolymers may contain minor proportions of other monomers, e.g. methyl methacrylate, cyclohexyl acrylate and vinyl carbazole. The butadiene copolymer may be supplemented by other rubbery polymers, e.g. copolymers of butadiene and styrene or acrylonitrile, polychloroprene, polybutadiene and polyacrylates. The polymerization is preferably carried out by dissolving the butadiene copolymer in the styrene-containing monomeric material with the aid, if desired, of an organic solvent, and heating the mixture in the presence of a catalyst, e.g. di-tert.-butyl peroxide, benzoyl peroxide or azodiisobutyronitrile. Also present during polymerization may be regulators and lubricants.
