摘要： A production method of polymer particles produces graft polymer particles by contacting a coagulant with a polymer latex (A) obtained by graft polymerizing a monomer containing methylmethacrylate to a rubber-like polymer. The method comprises a coagulation step in which polymer latex (A) is discharged into a stirring tank from an immersed nozzle provided so that the cross-sectional surface area of the discharge portion is 40 mm2 or more and the direction of discharge is facing in the same direction as the flow in the stirring tank and so that the linear velocity at the nozzle outlet is a velocity of 50-350 mm/s, and contacted with a coagulant to coagulate the graft polymer and obtain a slurry liquid; and a solidification step in which the resulting slurry liquid is held at a temperature of 60-100° C. to solidify the coagulated graft polymer. According to the production method of the present invention, graft polymer particles having superior powder characteristics with few coarse particles and high bulk specific gravity can be obtained without requiring the use of organic solvent or special equipment. Accordingly, polymer particles having superior powder characteristics can be produced in a stable manner and at low cost.
