The present invention relates to a graft copolymer, a method for preparing the same, and a thermoplastic resin composition including the same, and more particularly, a hard particle having an average particle diameter of 150 to 300 nm by administering a cationic emulsifier when preparing a polymer latex having a refractive index of at least 1.5. Preparing a polymer seed, copolymerizing an alkyl acrylate monomer mixture to the polymer latex seed to produce a composite rubber polymer core having an average particle diameter of 300 to 600 nm, and forming a graft shell layer in the presence of the core It relates to a method for producing a graft copolymer comprising a and a thermoplastic resin composition comprising the same. According to the present invention, there is an advantage in that a large diameter rubber polymer latex can be produced in a short time, and when the graft copolymer of the present invention is mixed with a hard matrix, the effect of providing a thermoplastic resin composition excellent in weatherability, colorability and impact resistance is provided. have. |
