Abstract

The present invention relates to thermoplastic moulding compositions consisting of polycarbonates, graft polymers and copolymers, which are characterized in that they contain special graft polymers and/or special copolymers, with the result that these moulding compositions possess a very homogeneous rubber distribution and furthermore possess very good toughness and heat stability and substantially improved heat distortion resistance.
