POLYMER RESIN COMPOSITION HAVING EXCELLENT IMPACT RESISTANCE OR HEAT RESISTANCE

摘要

The present invention relates to a polymer resin composition for providing a synthetic resin expressing physical properties such as improved heat resistance, impact resistance, or the like. The present invention can provide a polymer resin composition comprising a polyester copolymer including residues of dicarboxylic acid components having terephthalic acid, and residues of diol compositions having dianhydrohexitol; and one or more types of copolymers selected from the group consisting of an unsaturated nitrile-diene-based rubber-aromatic vinyl graft copolymer, an alkyl methacrylate-diene-based rubber-aromatic vinyl graft copolymer, and an alkyl methacrylate-silicone/alkyl acrylate graft copolymer.
