Abstract

Thermoplastic molding materials contain A) from 5 to 95% by weight of a partly aromatic, semicrystalline copolyamide composed essentially of PA1 a.sub.1) from 30 to 44 mol % of units which are derived from terephthalic acid PA1 a.sub.2) from 6 to 20 mol % of units which are derived from isophthalic acid PA1 a.sub.3) from 43 to 49.5 mol % of units which are derived from hexamethylenediamine and PA1 a.sub.4) from 0.5 to 7 mol % of units which are derived from aliphatic cyclic diamines of 6 to 30 carbon atoms, the molar percentages of components a.sub.1) to a.sub.4) together being 100%, and B) from 5 to 95% by weight of a polyphenylene ether C) from 0 to 30% by weight of an elastomeric polymer, D) from 0 to 45% by weight of a fibrous or particulate filler or of a mixture thereof, E) from 0 to 20% by weight of a flameproofing agent and F) from 0 to 30% by weight of conventional additives and processing assistants, the percentages A) to F) summing to 100%.
