摘要:
Silicone rubbers in the form of crosslinked, particulate particles can be used as a grafting base for the preparation of thermoplastic moulding materials having good low-temperature impact strength and resistance to weathering-ageing, after they are provided with an intermediate shell of crosslinked acrylate rubber.
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.
摘要:
The present invention relates to thermoplastic moulding compositions containing thermoplastic polycarbonates, graft polymers, rubber-free copolymers and, if appropriate, copolymeric rubbers, and also, if appropriate, conventional additives, which are characterized in that the rubber-free copolymers contain internal epoxide compounds.
