Thermoplastic resin composition

Abstract

Abstract PURPOSE:To prepare a composition having high heat deformation temperature and decomposition temperature, and excellent impact resistance, by compounding an N-substituted phenyl maleimide copolymer with a specific graft copolymer. CONSTITUTION:The objective composition is prepared by compounding (A) 20- 95pts.wt., preferably 30-90pts.wt. of a copolymer obtained by the copolymerization of 10-90wt% N-substituted phenyl maleimide with 90-10wt% vinyl monomer copolymerizable therewith with (B) 80-5pts.wt., preferably 70-10pts.wt. of a graft copolymer obtained by the polymerization of 80-20wt% monomer mixture consisting of styrene and at least one vinyl monomer copolymerizable therewith in the presence of 20-80wt% rubber polymer. The vinyl monomer in the component (A) is preferably styrene, methyl methacrylate, etc.
