Abstract: Impact-resistant thermoplastic molding materials are produced by graft polymerization of styrene, acrylonirtils and/or methyl methacrylate onto a rubber latex. The rubber latex employed has a mean particle size of less than 0.15 .mu. and is agglomerated partially, before grafting, by addition of an acrylic ester polymer dispersion. The molding materials obtained exhibit an optimum combination of mechanical properties obtained be converted to shaped articles by extrusion, deep-drawing or injection molding.

Abstract: An ABS molding material comprising a copolymer matrix A in which is dispersed a graft copolymer B. The graft copolymer B is composed of styrene and acrylonitrile as the grafting monomers on polybutadiene as a grafting base and has a mean particle diameter of from 0.2 to 0.45 .mu.m (d50value of the cumulative mass distribution). The gel component, isolated from the molding materials, is required to have a spin-spin relaxation time of from 0.7 to 1.5 .mu.s, so that the molding materials have a high surface gloss coupled with good notched impact strength even at low temperatures. The copolymer A can be a copolymer of styrene and acrylonitrile or a terpolymer additionally containing .alpha.-methylstyrene. The molding material can furthermore contain conventional additives. The molding materials according to the invention can be employed where great toughness coupled with high gloss is required, as in household appliances and in the automotive industry.

Abstract: ANTISTATIC THERMOPLASTIC MOLDING MASSES 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 styreneacrylonitrile copolymers.
