The present invention relates to a polymer resin composition that is capable of providing an environmentally friendly biomass-containing synthetic resin having improved chemical resistance. The present invention provides a polymer resin composition including: a polyester copolymer including a residue of a dicarboxylic acid component containing terephthalic acid, and a residue of a diol component including dianhydrohexitol; and one or more 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, and which has a tensile strength loss defined in the following Equation 1 ranging from 0.5 to 30%.
Tensile Strength Loss (%)=[(Tensile Strength before Test−Tensile Strength after Test)/Tensile Strength before Test]×100 [Equation 1]
