Abstract
Thermoplastic molding materials contain, based in each case on the sum of components A, B and C, A: from 10 to 90% by weight of a polymer A composed of styrene and/or substituted styrene, B: from 10 to 90% by weight of a polyolefin B and 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.

A thermoplastic molding material containing, based in each case on the sum of components A, B and C,
- A:
- from 10 to 90% by weight of a polymer A composed of styrene or substituted styrene,
- B:
- from 10 to 90% by weight of a polyolefin B and
- C:
- from 5 to 40% by weight of a star block copolymer C containing not less than 50% by weight of a styrene and prepared by anionic polymerization of styrene and butadiene or isoprene, coupling and subsequent selective hydrogenation, whereby only the double bonds originating from the monomer building blocks of butadiene and/or isoprene are saturated, and not the styrene component, so that more than 50% of the double bonds originally present are saturated.
