Abstract

Thermoplastic molding compositions are obtainable by mixing PA0 A) from 0.5 to 5% by weight of a thermoplastic polyester elastomer and PA0 B) from 0 to 50% by weight of fibrous or particulate fillers or mixtures thereof into a melt of PA0 C) from 40 to 99.5% by weight of a polyamide prepolymer having a viscosity number of from 40 to 80 ml/g and subsequent postcondensation in solid phase.
