Abstract
A method of producing resin powder in which a resin solution prepared by dissolving a resin in a water-miscible solvent is sprayed from a nozzle while spraying water from another nozzle located close to the first-said nozzle so as to form fine emulsified droplets of said resin solution in water, then at least a substantial portion of the water-miscible solvent in said emulsified droplets is rapidly transferred into water to produce a suspension of resin powder. The suspension is then filtered. Apparatus for practicing this method is also provided.
