Abstract

Thermoplastic molding materials contain, based in each case on the sum of components A, B and C, PA1 A: from 10 to 90% by weight of a polymer A composed of styrene and/or substituted styrene, PA1 B: from 10 to 90% by weight of a polyolefin B and PA1 C: from 5 to 40% by weight of a star block copolymer C containing not less than 50% by weight of styrene and prepared by anionic polymerization of styrene and butadiene and/or isoprene, coupling and subsequent selective hydrogenation.
