| 摘要 |
The present invention relates to a polymer resin composition capable of providing an environmentally friendly biomass-containing synthetic resin having improved chemical resistance. Provided in the present invention is a high thermal resistant polymer resin composition having excellent chemical resistance, which includes a polyester copolymer including a residue of dicarboxylic acid including terephthalic acid, and a residue of diol including dianhydrohexytol; one or more kinds of copolymer 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-silicon/alkyl acrylate graft copolymer; and polytrimethylene terephthalate. The composition is represented by general formula 1, where loss rate of tensile strength (%)=[(tensile strength before test-tensile strength after test)/tensile strength before test]×100, and has the loss rate of tensile strength of 0.5-20%. |
