Abstract

Rubber modified styrene-acrylonitrile polymers (ABS) having three different types of rubber particles. One type is small, usually emulsion-produced particle. The second is a large emulsion-produced particle. The third is a large, mass-produced particle. Such compositions exhibit good combinations of toughness and gloss.
