MANUFACTURING METHOD OF POLYMER PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method capable of stably manufacturing a polymer particle with a high degree of crystallinity and less residual monomers.SOLUTION: A manufacturing method of a polymer particle includes: a step of supplying a material for polymerization reaction including a monomer and compressive fluid into a reaction vessel; a polymerization step of polymerizing the monomer inside the reaction vessel to generate a polymer; and a granulation step of applying a shear force while crystallizing the polymer to a degree higher than a degree of crystallinity with which fluid of the polymer obtained at the polymerization step is solidified to granulate the polymer.SELECTED DRAWING: None
