Abstract

A rubber-modified, impactresistant acrylonitrile-butadiene-styrene (ABS) molding material, as obtained by polymerizing styrene and acrylonitrile in the presence of a preformed rubber, dissolved in monomeric styrene and acrylonitrile and, if necessary, a solvent, wherein the rubber is a styrene-butadiene block copolymer and at least one further polymer which is compatible with the styrene-butadiene block rubber or its polystyrene component and is incompatible with polystyrene-acrylonitrile.
