| 主权项 | 1. A particle manufacturing method, comprising: polymerizing a ring-opening-polymerizable monomer after bringing the ring-opening-polymerizable monomer into contact with a first compressible fluid comprising carbon dioxide via a ring-opening polymerization to obtain a polymer; and granulating the polymer by jetting the polymer with a second compressible fluid comprising nitrogen supplied to the polymer. | ||
