    摘要: This invention provides a process for producing fine PPS resin particles and a dispersion thereof by industrially applicable simple operation. This invention further provides very fine PPS resin particles, and furthermore provides fine PPS resin particles uniform in particle size.This invention is a process for producing fine polyphenylene sulfide resin particles comprising the following steps (a) and (b):(a) A step of heating a polyphenylene sulfide resin in an organic solvent, for obtaining a solution with the polyphenylene sulfide resin dissolved therein (dissolution step) (b) A step of flush-cooling the aforementioned solution, for precipitating the fine particles of the polyphenylene sulfide resin (precipitation step).
