METHOD FOR PRODUCING AQUEOUS DISPERSION OF PERFLUORO RUBBER

摘要

PROBLEM TO BE SOLVED: To provide a new production method capable of producing an aqueous dispersion containing particles of perfluoro rubber by one-stage polymerization, without using a long chain fluorine-containing surfactant such as ammonium perfluorooctanoate.SOLUTION: The method for producing an aqueous dispersion of perfluoro rubber is characterized by producing an aqueous dispersion containing particles of perfluoro rubber by performing polymerization of a fluoro monomer in an aqueous medium, in the presence of a fluorine-containing surfactant having a LogPOW of 3.4 or less and a polymerization initiator.
