Abstract

Thermoplastic molding masses based on the copolymerization of styrene and/or .alpha.-methylstyrene and acrylonitrile, which may be modified to be impact resistant with rubberlike polymers, are made antistatic by adding 0.01 to 1.5 percent by weight of a graft polyol which is a polyhydroxy-polyalkylene polyether modified with styrene-acrylonitrile copolymers.
