Method for producing particles containing fluorinated polymer

Abstract

To provide a method for producing particles containing a fluorinated polymer, by which particles containing a fluorinated polymer with a low content of impurities, can be produced. The method for producing particles containing a fluorinated polymer of the present invention is a method for producing particles containing a fluorinated polymer having groups convertible to ion exchange groups, which comprises preparing a liquid composition containing the fluorinated polymer and a first solvent, and mixing the liquid composition with a second solvent that is an olefin having a fluorine atom and a chlorine atom, to agglomerate the fluorinated polymer thereby to form particles containing the fluorinated polymer.
