Abstract

See full text

To provide a method for producing particles, which contains: bringing a compressive fluid and a pressure plastic material into contact with each other using a multistage split flow micromixer, to thereby produce a melt of the pressure plastic material, in which the compressive fluid is dissolved; and jetting the melt of the pressure plastic material, to form particles, wherein the pressure plastic material is a resin having a carbonyl structure —C(═O)—, and wherein a viscosity of the melt is 500 mPa·s or lower, as measured under temperature and pressure conditions at the time of the jetting the melt of the pressure plastic material.
