METHOD FOR PREPARING RUBBERY POLYMER LATEX

摘要

PURPOSE: A method for preparing a rubbery polymer latex for producing ABS (acrylonitrile-butadiene-styrene) resins is provided to obtain a resin having excellent impact resistance at a low temperature. CONSTITUTION: The method for preparing a rubbery polymer latex comprises the steps of: (a) introducing 50-95 parts by weight of an aliphatic conjugated diene compound to be used as a monomer in one portion before initiating polymerization and reacting it; and (b) introducing 5-50 parts by weight of the aliphatic conjugated diene compound, when the gel content of the latex reaches 1% to 65%, to perform emulsion polymerization of a large-diameter rubbery polymer latex.
