Abstract

Thermoplastic molding compositions contain as essential components PA0 A) 40-95% by weight of a partly aromatic copolyamide composed essentially of PA1 A.sub.1) 20-90% by weight of units derived from terephthalic acid and hexamethylenediamine, PA1 A.sub.2) 0-50% by weight of units derived from .epsilon.-caprolactam and PA1 A.sub.3) 0-80% by weight of units derived from adipic acid and hexamethylenediamine, PA0 B) 5-60% by weight of an impact modifying rubber, and in addition PA0 C) 0-50% by weight of fibrous or particulate fillers or mixtures thereof.
