ABSTRACT:
Improved combinations of gloss and toughness are obtained in rubber-modified, impact-resistant monovinylidene aromatic polymer compositions when mass-produced particles consisting of a blend of polybutadiene with a block copolymer rubber are dispersed therein. Advantageously, the rubber-modified polymer compositions also comprise one or more groups of emulsion-produced rubber particles.
