METHOD FOR PRODUCING RESIN FINE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing resin particles capable of obtaining the resin particles having a high sphericity and uniform particle diameter easily.

SOLUTION: The method for producing resin particles is provided by heating and/or pressurizing a mixture of the resin with a fluid not dissolving the resin at a normal temperature and pressure, and having a process 1 of making at least one component of the liquid state fluid as a supercritical state or semi-supercritical state and a process 2 of lowering the temperature of the liquid state fluid and releasing the pressure.
