Abstract

A thermoplastic molding material which is made up of components A, B, C, and D. Component A comprises 10-90% of the composition and is a copolymer made up of 30-95% styrene; 4-40% (meth)acrylonitrile, methyl methacrylate, or maleic anhydride; 1-30% of a monomer described by formula in the specification, N-vinylimidazole or N-vinylcarbazole; and up to 40% of a copolymerizable ethylenically unsaturated monomer. Component B comprises 10-90% of the composition and is a copolymer made up of 50-99.9% of an alpha-olefin; 0.1-50% of a monomer containing acid groups; and up to 40% of a copolymerizable ethylenically unsaturated monomer. Component C comprises up to 80% of the composition and is a copolymer made up of 50-95% styrene and 5-50% (meth)acrylonitrile, methyl methacrylate or maleic anhydride. Component D comprises up to 80% of the composition and is made up of a polycarbonate. All percentages are by weight.
