Process for producing polymer particles and elastic process for producing a resin composition that contains

A process for producing a resin composition comprising particles of elastic polymer (A) dispersed in a polymerizable organic compound (H) having a reactive functional group, comprising: carrying water (D) in contact with a mixture (C) obtained mixing an aqueous latex of particles elastic polymer (A) with an organic solvent (B) exhibiting partial solubility in water; thereby forming a flocculate (F) of the elastic polymer particles containing the organic solvent (B) in an aqueous phase; then separating the flocculated (F); adding an organic solvent which exhibits affinity particles elastic polymer (A) to flocculate (F); bringing the dispersion (G) wherein the elastic polymer particles (A) are dispersed in the organic solvent (B) is obtained; mixing the dispersion (G) and the polymerizable organic compound (H); and then removing the volatile ingredients by evaporation.
