Thermoplastic moulding compounds A b s t r a c t Thermoplastic moulding compounds containing A) ABS-type resin, B) aromatic polycarbonate resin, C) polymer resin bearing carboxyl groups and optionally D) further polymer resins, characterised in that an ABS resin with at least one basically acting additive is used as component A, component C is selected from C.1) a polymer resin with a carboxyl group (-COOH) content of 40 to 62.5 wt.%, which is derived from acrylic acid polymers or methacrylic acid polymers or acrylic/methacrylic acid copolymers or C.2) a polymer resin with a carboxyl group (-COOH) content of 5 to 30 wt.% which was obtained by polymerisation of at least two monomers selected from styrene, acrylonitrile and acrylic acid esters and/or methacrylic acid esters with acrylic acid and/or methacrylic acid and the weight ratio of basically acting additive in A) : carboxyl groups in C) has a value of 5:1 to 1:1 (when using polymer resin C.1) or a value of 3:1 to 1:3 (when using polymer resin C.2).
