Abstract
Disclosed is an ABS type polyblend composition exhibiting improved physical properties, which comprises from about 5 to 60% by weight of a copolymer of styrene and acrylonitrile; from about 10 to 70% by weight of a graft copolymer of styrene, acrylonitrile, and a butadiene polymer having an average rubber particle size of from about 1 to 10.mu.; and from about 10 to 70% of a high butadiene content backbone copolymer of styrene, acrylonitrile, and a butadiene polymer having an average rubber particle size of less than abut 0.5.mu., the ratios of the backbone copolymer and the styrene-acrylonitrile-butadiene polymer copolymer being adjusted such that from about 15 to 25% by weight of the total butadiene polymer content of the polyblend is provided by the larger rubber particle size graft copolymer.
