Transparent heat-resistant thermoplastic resin composition

Abstract

Abstract PURPOSE:To provide the titled composition composed of a specific imidated copolymer and a carbonate resin and having excellent heat-resistance and improved oil-resistance, hot-water resistance and moldability of the polycarbonate resin. CONSTITUTION:(A) An imidated copolymer composed of 30-90(wt)% aromatic vinyl monomer residue, 3-70% unsaturated dicarboxylic acid imide derivative residue and 0-40% other vinyl monomer residue and produced e.g. by copolymerizing an aromatic vinyl monomer (preferably styrene), an unsaturated dicarboxylic acid anhydride (preferably maleic anhydride) and optionally a vinyl monomer copolymerizable therewith (preferably acrylonitrile, etc.) and reacting the obtained polymer with 0.8-1.05mol-equivalent (based on the acid anhydride group in the polymer) of ammonia, etc., to effect the imidation of the polymer is compounded with (B) a polycarbonate resin preferably based on bis(hydroxyaryl)-alkane-based polycarbonate. The amounts of the components A and B are 5-95% and 95-5%, respectively.
