Abstract

The present invention relates to a thermoplastic resin composition, a method of preparing the same, and a molded article manufactured using the same. More specifically, the thermoplastic resin composition of the present invention includes 100 parts by weight of a base resin consisting of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-1) containing acrylate rubber having an average particle diameter of 0.05 to 0.15 μm as a core, an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-2) containing acrylate rubber having an average particle diameter of 0.3 to 0.6 μm as a core, an aromatic vinyl polymer (B-1), and a heat-resistant aromatic vinyl polymer (B-2); and 0.5 to 10 parts by weight of a polyolefin elastomer (C). Within this range, the thermoplastic resin composition may have a heat deflection temperature (HDT) of 89° C. or more.
