|1. (WO2018181377) METHOD FOR PRODUCING FLUOROPOLYMER-CONTAINING POWDER PARTICLES|
|Title:||METHOD FOR PRODUCING FLUOROPOLYMER-CONTAINING POWDER PARTICLES|
Provided is a method for producing fluoropolymer-containing powder particles having a small particle size and a narrow particle size distribution. In this method for producing fluoropolymer-containing powder particles, an aqueous solution containing water, an organic solvent, and a fluoropolymer, which contains a fluoroolefin-based unit and a unit having a carboxy group, is concentrated under reduced pressure to obtain a mother liquid containing fluoropolymer-containing powder particles, and the mother liquid is filtered to obtain fluoropolymer-containing powder particles, wherein the organic solvent is methanol, ethanol, propanol, butyl alcohol, ethylene glycol dimethyl ether, tetrahydrofuran, acetone, methyl ethyl ketone, or acetonitrile.
