TERPOLYMER HAVING IMPROVED HEAT RESISTANCE AND THERMOPLASTIC RESIN COMPOSITION INCLUDING SAME

摘要

Maleic acid anhydride-aromatic group vinyl-unsaturated nitrile terpolymer, according to the present invention, comprises (A) 60-80 wt% of an aromatic vinyl-based monomer; (B) 15-30 wt% of an unsaturated nitrile-based monomer; and (C) 3-15 wt% of maleic acid anhydride, is a terpolymer whose content ratio of nitrile based-monomer is 0.23-0.5 for the aromatic group vinyl-based monomer and has a single glass transition temperature and excellent heat resistance.
