Abstract

Thermoplastic molding materials contain, as essential components, PA0 (A) from 10 to 89.99% by weight of a polyester, PA0 (B) from 10 to 89.99% by weight of a polycarbonate and PA0 (C.sub.1) from 0.01 to 1% by weight of a low molecular weight organic compound of not more than 70 carbon atoms which contains (--SO.sub.3).sub.m Q groups where Q is hydrogen, NH.sub.4 or an alkali or alkaline earth metal and m is an integer equal to the valency of Q, and/or PA0 (C.sub.2) from 0.01 to 30% by weight of a polymer containing sulfo groups and having a weight average molecular weight of not less than 1000, PA0 and, as a further component, PA0 (D) from 0 to 30% by weight of a rubber impact modifier.
