Abstract:
The present invention relates to a graft copolymer, a method for preparing the same and a thermoplastic resin composition comprising the same. The graft copolymer of the present invention comprises a composite rubber polymer (A-1) having an average particle diameter of 250-600 nm prepared by particle enlargement after mixing a diene rubber polymer (a-1) latex having an average particle diameter of 50-150 nm and a core-shell structured, cross-linked alkyl acrylate rubber polymer (b-1) latex having an average particle diameter of 50-250 nm. A thermoplastic resin composition prepared by mixing the graft copolymer of the present invention with a hard matrix (B) has very superior weathering resistance and superior pigmentation property, gloss, impact resistance and low-temperature impact strength.
