Method for producing polymer microparticles |
| abstract |
Provided is a method of producing polymer particles characterized in that, 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 with the polymer A as a major component and a solution phase containing the polymer B as a major component, the polymer A, the polymer B, and the organic solvent are continuously supplied to a mixing apparatus to thereby allow an emulsion to be formed; the emulsion is supplied to a vessel and added continuously with a poor solvent for the polymer A in the vessel to allow the polymer A to precipitate ; and polymer A particles is continuously taken from the vessel. The present invention provides a method that allows for mass production by efficient processes of manufacturing and that continuously microparticulates and produces polymer particles with lower variability in the average particle diameter and a smaller particle diameter distribution index. |
