Abstract
The present invention relates to a method of preparing an ABS-based graft copolymer having improved impact strength and an ABS-based injection-molded article including the same. More particularly, the present invention provides an ABS-based copolymer resin having improved impact strength by optimizing structures of large-diameter diene-based rubber latex particles and a matrix structure between ABS-based copolymer particles and a SAN resin through introduction of a multimeric acid of an unsaturated fatty acid or a metal salt thereof as an emulsifier in a large-diameter diene-based rubber latex polymerization step and an ABS graft polymerization step.
