Abstract: A process for efficiently producing an agglomerate resulting from removal of impurities from a water-base latex of rubbery polymer particles or dry powder thereof and producing a dispersion having rubbery polymer particles dispersed in an organic solvent, and a process for efficiently producing a resin composition of low impurity content, in which the state of dispersion of rubbery polymer particles is excellent, from the above dispersion. In particular, a rubbery polymer particle agglomerate of low impurity content is obtained by first mixing a water-base latex of rubbery polymer particles with an organic solvent exhibiting partial solubility in water, bringing the resultant mixture into contact with water to thereby form a rubbery polymer particle agglomerate, and thereafter separating the water phase from the agglomerate/water phase mixture.
