Abstract

Thermoplastic molding materials contain PA1 A) from 10 to 97% by weight of a polyoxymethylene homo- or copolymer, PA1 B) from 3 to 50% by weight of a thermoplastic elastomer selected from the group consisting of the thermoplastic polyurethanes, the polyetheresters and the polyetheramides, the flexible phase of which is derived from polyetherpolycarbonatediols, PA1 C) from 0 to 50% by weight of a fibrous or particulate filler or a mixture thereof and PA1 D) from 0 to 30% by weight of conventional additives or processing assistants.
