Method for producing diene rubber latex, method for producing ABS graft copolymer containing the same, and method for producing ABS injection molded article
The present invention relates to 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. More particularly, the present invention relates to a method of 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, a method of preparing an ABS-based graft copolymer including the same, and a method of manufacturing an ABS-based injection-molded article. In accordance with the present invention, polymerization stability and productivity of a latex may be improved and, when the latex is included upon production of an ABS-based resin, improved mechanical properties, gloss, and clearness may be provided.
