PROCESS FOR PRODUCING AQUEOUS DISPERSION OF COMPOSITE FLUOROPOLYMER PARTICLE, AQUEOUS DISPERSION, AND COMPOSITE POLYMER PARTICLE

摘要

There is provided an aqueous dispersion comprising fluorine-containing composite polymer particles which, even when an amount of a fluorine-containing polymer is smaller than that of conventional fluorine-containing polymer, makes it possible to obtain characteristics of the fluorine-containing polymer equal to or superior to those of conventional fluorine-containing polymer, and a process for preparing the aqueous dispersion. The process, which is used for preparing an aqueous dispersion comprising fluorine-containing composite polymer particles, is characterized by subjecting the polymer solution obtained by dissolving the fluorine-containing polymer (A) in the monomer (b) having an ethylenically unsaturated group to emulsion polymerization.
