Abstract: The present invention relates to a method for preparing rubber latex. The method of the present invention is characterized in that hard polymer seed is fed into a polymerization reactor equipped with a condenser before the commencement of polymerization and that the condenser is operated from the start of the polymerization, so that the condensate containing the conjugated diene compound is fed into the polymerization reactor with the commencement of the polymerization. In accordance with the method for preparing rubber latex of the present invention, it is possible to prepare core-shell type rubber latex capable of maximizing surface grafting ratio of rubber latex without sacrificing uniformity of polymerization system and particle stabilization and prepare resin having superior impact resistance, coloring property and appearance property(luster), when applied to ABS resins.
