Title: METHOD FOR PREPARING ABS GRAFT COPOLYMER HAVING ENHANCED IMPACT STRENGTH AND METHOD FOR PREPARING ABS INJECTION-MOLDED PRODUCT COMPRISING SAME
Abstract:
The present invention relates to a method for preparing an ABS graft copolymer having enhanced impact strength, and an ABS injection-molded product comprising same. More specifically, the present invention enables optimization of a matrix structure between ABS copolymer particles and a SAN resin and a large-diameter diene-based rubber latex particle structure by means of introducing a polymer acid of unsaturated fatty acid or metal salts of same as an emulsifier to a large-diameter diene-based rubber latex polymerization step and an ABS graft polymerization step, and thus can provide an ABS copolymer resin having enhanced impact strength.
