Abstract:
Provided is a method for producing a fluoropolymer in the presence of a specific non-fluorinated compound having surface activity. The method shows a high polymerization rate, and suppresses formation of sticking polymerization materials after production of a polymer product. The method includes aqueous dispersion polymerization of a fluoroolefin in the presence of a compound (1) represented by formula (1): wherein R1 and R2 are the same as or different from each other, and each represent a C4 to C12 non-fluorinated saturated hydrocarbon group; and M is an alkali metal, an ammonium salt, or an amine salt.
