METHOD FOR PRODUCING HOLLOW FINE PARTICLES, HOLLOW FINE PARTICLES, PHASE-SEPARATED FINE PARTICLES, AQUEOUS DISPERSION, AND COMPOSITION
20260035554 · 2026-02-05 · ·

A production method capable of producing a hollow fine particulate containing a perfluororesin, having a large average particle size, and having a monoporous structure. A method for producing a hollow fine particulate including: a step A of dispersing a solution containing a perfluoromonomer and a non-polymerizable solvent capable of dissolving the perfluoromonomer and having an SP value of 9.00 to 9.80 (cal/cm.sup.3).sup.1/2 into water to provide a dispersion; a step B of polymerizing the perfluoromonomer to provide a phase-separated fine particulate containing a perfluororesin and having a monoporous structure; and a step C of removing the non-polymerizable solvent in the phase-separated fine particulate to provide a hollow fine particulate having a monoporous structure.
