Abstract
A polymer resin composition capable of providing a synthetic resin showing physical properties of improved heat resistance or impact resistance is provided, in which the polymer resin composition includes a polyester tetrapolymer containing a residue of a dicarboxylic acid component containing terephthalic acid and a residue of a diol component containing dianhydrohexitol, and one or more terpolymers selected from the group consisting of an unsaturated nitrile-diene-based rubber-aromatic vinyl graft terpolymer, an alkyl methacrylate-diene-based rubber-aromatic vinyl graft terpolymer, and an alkyl methacrylate-silicone/alkyl acrylate graft terpolymer.
