Abstract

Thermoplastic molding materials contain PA1 A) from 50 to 99% by weight, based on the total weight of the molding material, of a toughened polymer, PA1 B) from 1 to 20% by weight, based on the total weight of the molding material, of a blend of PA2 B.sub.1) a copolymer comprising polymerized units which are derived from a polymerizable carboxylic acid or derivatives thereof and PA2 B.sub.2) a polyamide, PA1 C) from 0 to 40% by weight of a fibrous or particulate filler or of a mixture thereof and PA1 D) from 0 to 20% by weight of conventional additives and processing assistants.
