IMPACT STRENGTH MODIFIER FOR THERMOPLASTIC AROMATIC POLYCARBONATE, THERMOPLASTIC MOLDING MATERIAL AND MOLDED BODY

摘要

The impact modifier is a copolymer comprising an elastomer and a methyl methacrylate copolymer which are covalently bonded to one another, the methyl methacrylate copolymer being compatible per se, through certain comonomers, with polycarbonate resin. These comonomers are aromatic (meth)acrylates and (meth)acrylamides, cycloalkyl (meth)acrylamides and cycloalkyl maleimides. The novel impact modifiers are used in thermoplastic moulding compositions containing polycarbonate.
