PURPOSE:To provide the subject polyester-based resin composition excellent in heat resistance, impact resistance and the balance of physical properties such as elongation and stiffness. CONSTITUTION:A thermoplastic resin composition characterized by its composition composed of (A) 10-50wt.% maleimide-based polymer composed of 30-70mol% styrene unit, 25-47mol% maleimide-based monomer unit and 3-25mol% maleic anhydride monomer unit, (B) 35-75wt.% aromatic polyester resin, (C) 5-20wt.% polycarbonate resin and (D) 3-40wt.% copolymer composed of 80-99.5wt.% vinyl monomer unit and 0.5-20wt.% epoxy group-containing vinyl monomer unit. The above-mentioned resin composition in this invention is excellent in heat resistance, impact resistance, the balance of physical properties such as elongation and stiffness and moldability and capable of producing a molding excellent in its visual appearance. |
