摘要:
A method of producing polymer particles includes, in a system in which a polymer A and a polymer B are dissolved in and mixed with an organic solvent to undergo phase separation into two phases which are a solution phase containing the polymer A as a major component and a solution phase containing the polymer B as a major component, continuously adding an emulsion including the polymer A, the polymer B and the organic solvent, and a poor solvent for the polymer A to a vessel continuously to allow the polymer A to precipitate; and separating polymer A particles from the vessel continuously.
