    摘要： The present invention relates to a graft copolymer having excellent thermal stability, a method of preparing the graft copolymer, a thermoplastic resin composition including the graft copolymer, and a molded part including the thermoplastic resin composition. More specifically, the present invention relates to a graft copolymer having a core-shell structure and having excellent thermal stability, which is prepared according to an emulsion polymerization method, in which a metal salt of sorbic acid is included in reactants in a specific amount and is used as an emulsifier. According to the method, thermal stability of a graft copolymer can be improved by using the metal salt of sorbic acid, which can be easily removed in a dehydration process, instead of a conventional emulsifier, which remains in a reaction product after completion of emulsion polymerization and lowers thermal stability of a prepared graft copolymer.
    In addition, according to the present invention, since the thermoplastic resin composition of the present invention includes the graft copolymer having excellent thermal stability, the thermoplastic resin composition and the molded part manufactured using the thermoplastic resin composition have excellent physical properties, such as impact strength, fluidity, and transparency. Furthermore, the degree of discoloration that may occur when the resin composition or the molded part is allowed to stay in an injection molding machine or stay at a high temperature for a long period of time may be reduced.
