Abstract

The present invention relates to a thermoplastic resin composition, a method of preparing the same, and an injection-molded article including the same. More particularly, the present invention relates to a thermoplastic resin composition having superior vibration welding properties along with ABS-based resin-specific impact resistance, heat resistance, and the like due to inclusion of an ABS-based graft copolymer including a conjugated diene-based rubber polymer having an average particle diameter of 0.25 to 0.35 μm; a rubber-modified graft copolymer including a diene-based rubber polymer having an average particle diameter of 0.6 to 10 μm and prepared by continuous bulk polymerization; and a matrix resin, and an injection-molded article including the thermoplastic resin composition.
