Abstract
A method for producing polymer particles, including (A) polymerizing and granulating a ring-opening polymerizable monomer in a compressive fluid with a catalyst in the presence of a surfactant, or (B) polymerizing and granulating an addition polymerizable monomer in a compressive fluid in the presence of a silicone surfactant.

A method for producing polymer particles, comprising:
- (A) polymerizing a ring-opening polymerizable monomer to produce a polymer while granulating the polymer in a compressive fluid with a catalyst in the presence of a surfactant, or
- (B) polymerizing an addition polymerizable monomer to produce a polymer while granulating the polymer in a compressive fluid in the presence of a silicone surfactant.
Polymer particles obtained by a method comprising:
- (A) polymerizing a ring-opening polymerizable monomer to produce a polymer while granulating the polymer in a compressive fluid with a catalyst in the presence of a surfactant, or
- (B) polymerizing an addition polymerizable monomer to produce a polymer while granulating the polymer in a compressive fluid in the presence of a silicone surfactant.
