Abstract: Molding materials containing styrene-acrylonitrile copolymers, in which an additional essential ingredient is from 0.1 to 2.0% by weight, based on the copolymer, of a three-block polymer X-Y-X, where X is a terminal ethylene oxide block and Y is a central propylene oxide block. The proportion of terminal ethylene oxide blocks X, based on block copolymer, is from 5 to 20% by weight, while the central propylene oxide block Y has a number-average mean molecular weight of from 700 to 3,000 and its proportion is from 80 to 95% by weight, based on block copolymer. The number-average molecular weight of the sum of the two terminal blocks X is from 140 to 1,000. The novel molding materials may be used for the manufacture of moldings, since the three-block copolymer X-Y-X advantageously influences the processing characteristics of styrene-acrylonitrile copolymers, and in particular broadens the range of conditions under which they may be injection-molded, without adversely affecting the mechanical properties of the styrene-acrylonitrile copolymers. Accordingly, the injection molding scrap rate can be kept very low.
