The thermoplastic moulding materials contain A) an ABS-type resin, B) an aromatic polycarbonate resin, C) a carboxyl-carrying polymer resin, and optionally D) further polymer resins, characterised in that component A is an ABS resin containing at least one basic additive, component C is selected from C.1) a polymer resin containing from 40 to 62.5 % by weight of carboxyl groups (-COOH) which is derived from acrylic or methacrylic acid polymers or acrylic or methacrylic acid copolymers or C.2) a polymer resin containing from 5 to 30 % by weight of carboxyl groups (-COOH) which has been obtained by polymerisation of at least two monomers selected from styrene, acrylonitrile and acrylates and/or methacrylates with acrylic acid and/or methacrylic acid, and the weight ratio between the basic additive in A) and the carboxyl groups in C) has a value of 5:1 to 1:1 (when polymer resin C.1 is used) or a value of 3:1 to 1:3 (when polymer resin C.2 is used). |
