Abstract: A production method of polyvinylidene fluoride resin particles comprising: (Process a1) a process to precipitate the polyvinylidene fluoride resin particles by adding a 100 mass % solution in total consisting of 75 to 99 mass % organic solvent, 1 to 25 mass % water and 0.5 to 15 mass % polyvinylidene fluoride resin to a poor solvent of the polyvinylidene fluoride resin; or (Process a2) a process to precipitate polyvinylidene fluoride resin particles by performing a flash-crystallization of the solution. With such a configuration, PVDF resin particles can be industrially produced by simple operations without using surfactant agent.

Abstract: A fine polymer particle production method includes producing an emulsion in a liquid prepared by dissolving and mixing a polymer A and a polymer B in organic solvents in which a solution phase composed primarily of the polymer A and a solution phase composed primarily of the polymer B are formed as separate phases, and bringing it into contact with a poor solvent for the polymer A to precipitate the polymer A. This method serves for easy synthesis of fine polymer particles with a narrow particle size distribution and the method can be effectively applied to production of highly heat-resistant polymers that have been difficult to produce with the conventional methods.
