PROCESS FOR PRODUCING FINE PARTICLES

A process for producing fine particles is provided including the steps of (1) preparing a solution having a viscosity of 20 mPa·s or less at 25° C. by using a polymer and a first solvent, (2) mixing the solution with a second solvent to prepare an emulsion and (3) removing the first solvent from the...
