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.

Abstract: The present invention relates to a thermoplastic resin composition, more precisely, a thermoplastic resin composition with enhanced impact resistance, gloss, weather resistance and scratch resistance, compared with the conventional thermoplastic resin compositions, by containing an acrylate-styrene-acrylonitrile (ASA) graft copolymer, an aromatic vinyl compound and vinyl cyan compound copolymer, an alkyl methacrylate/aromatic vinyl compound/vinyl cyan compound terpolymer and a di-block copolymer (aromatic vinyl compound/vinyl cyan compound—alkyl methacrylate/aromatic vinyl compound/vinyl cyan compound).

Abstract: The present invention is related to a method of manufacture of a graft copolymer latex and its dried powder including a step of manufacture of a latex using a reactive surfactant for a surfactant in manufacturing of the graft copolymer latex containing acrylic polymers and a step of manufacture of dried powder in which the graft copolymer latex manufactured in the above step of manufacture of a latex is sprayed and dried. The method according to the present invention is effective in that it is possible to provide for dried powder of a graft copolymer latex having a low moisture content and a high powder density and to provide for a thermoplastic resin composition containing the above latex having superior luster, tensile strength, and thermal stability.
