METHOD FOR PRODUCING HOLLOW FINE PARTICLES, HOLLOW FINE PARTICLES, PHASE SEPARATED FINE PARTICLES, AQUEOUS DISPERSION, AND COMPOSITION

WIPO Patent Application WO/2023/058714

A1

The purpose of the present disclosure is to provide a production method by which it is possible to produce hollow fine particles which contain a fluorine-containing resin and have a large average particle diameter. This method for producing hollow fine particles includes: a step A for obtaining a dispersion liquid by dispersing a solution containing a fluorine-substituted monomer and a non-polymerizable solvent in water; a step B for obtaining phase separated fine particles containing a fluorine-containing resin by polymerizing the fluorine-substituted monomer; and a step C for obtaining hollow fine particles by removing the non-polymerizable solvent present in the phase separated fine particles.
