Abstract

Thermoplastic molding compositions containing PA0 A) ABS-type resin, PA0 B) aromatic polycarbonate resins, PA0 C) a compound bearing several carboxyl groups or mixtures thereof and optionally PA0 D) further polymer resins, characterized in that an ABS resin with at least one basically acting additive is used as component A, component C is selected from compounds having a molecular weight of from 150 to 260 having at least two carboxyl groups (--COOH) in the molecule, and the weight ratio of basically acting additive in A: carboxyl groups in C is from 5:1 to 1:1.
