ABS METHOD FOR PREPARING ACRYLONITRILE-BUTADIENE-STYRENE BASED GRAFT COPOLYMER AND METHOD FOR PREPARING THERMOPLASTIC RESIN COMPOSITION COMPRISING THE COPOLYMER

摘要

The present invention relates to a method for producing an ABS-based graft copolymer and a method for producing a thermoplastic resin composition comprising the same, and more particularly, a predetermined amount of a vinyl aromatic compound and a vinyl cyanide compound is added before the small-diameter rubber latex is enlarged. to a method for producing an ABS-based graft copolymer, characterized in that the rubber latex is enlarged by adding a polymer coagulant within a specific content range after partial grafting, and a method for producing a thermoplastic resin composition comprising the same. According to the present invention, the stability of the latex can provide the ABS-based graft copolymer, there is an advantage that the impact resistance is improved.
