PURPOSE: Provided is a thermoplastic resin composition for use in interior and exterior materials of cars, which has excellent dimensional stability at a high temperature, improved impact resistance, and excellent moldability and coating property. CONSTITUTION: The thermoplastic resin composition comprises: 30-70 wt% of a rubber latex; 10-30 wt% of a graft copolymer(I) comprising 70-30 wt% of a mixed monomer consisting of 20-40 wt% of a vinyl cyanide monomer and 60-80 wt% of an aromatic vinyl compound monomer; 20-50 wt% of a non-linear graft copolymer(II) consisting of 20-40 wt% of a vinyl cyanide monomer and 60-80 wt% of an aromatic vinyl compound monomer and having a weight average molecular weight of 200,000-1,000,000; and 20-60 wt% of a linear graft copolymer(III) consisting of 20-40 wt% of a vinyl cyanide monomer and 60-80 wt% of an aromatic vinyl compound monomer and having a weight average molecular weight of 100,000-200,000. |
