A process for preparing a synthetic resin powder having an improved blocking resistance suitable as a modifier for vinyl chloride resins, which comprises coagulating an aqueous latex of a graft copolymer suitable as a modifier for vinyl chloride resins, mixing the resulting, slurry with a latex of a specific polymer of methyl methacrylate, an aromatic vinyl compound, a crosslinkling monomer and optionally other copolymerizable monomers or a slurry formed from the specific polymer latex by coagulation, and recovering a powder from the resulting mixture containing the coagulated graft copolymer and the coagulated specific polymer. |
