Abstract
A method of preparing a diene-based rubber latex, a method of preparing an ABS-based graft copolymer including the same, and a method of manufacturing an ABS-based injection-molded article include preparing an in-situ bimodal rubber latex, in which a small-diameter polymer and a large-diameter polymer are formed in a desired ratio, by controlling contents, addition time points, and types of reactants when a conjugated diene based monomer, a crosslinking agent with a long linear chain end, an emulsifier including a multimeric acid of an unsaturated fatty acid or a metal salt thereof, and a molecular weight regulator are polymerized.
