摘要:
The present invention relates to thermoplastic moulding compounds based on thermoplastic polycarbonates, graft polymers and optionally thermoplastic copolymers, characterized in that the graft polymers contain at least one primary or secondary aliphatic acrylic acid ester or tert.-butyl acrylate or tert.-butyl methylacrylate incorporated by polymerization. The invention also relates to a process for the preparation of these thermoplastic moulding compounds.
