PROBLEM TO BE SOLVED: To provide an improved manufacturing method for a graft polymer latex, which can restrain the fouling of the inner wall of a reactor by the generation of adherent materials in the graft polymerization from occurring, and as a result, brings forth good productive efficiency and in addition contributes to industrial waste reduction. SOLUTION: In producing the graft polymer latex by performing emulsion graft polymerization of a vinyl monomer in the presence of a rubbery polymer latex, the rubbery polymer latex is beforehand heated to a temperature substantially higher than the reaction temperature in the emulsion graft polymerization and then supplied to the reactor for the emulsion graft reaction.
