    摘要: 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 R 1 and R 2 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.

    摘要: The present invention aims to provide a production method that can produce an aqueous dispersion containing polyvinylidene fluoride with high productivity. The present invention relates to a method of producing an aqueous dispersion of polyvinylidene fluoride, including: emulsion polymerization of vinylidene fluoride in the presence of a surfactant, an organic peroxide, and water to produce an aqueous dispersion that contains polyvinylidene fluoride. The surfactant has a surface tension of 55 mN/m or smaller when added in an amount of 1000 ppm.

    摘要: The present invention provides a method for producing a copolymer containing a perhaloolefin and vinyl acetate by a novel emulsion polymerization method. The present invention relates to a method for producing a perhaloolefin-vinyl acetate copolymer by emulsion polymerization of at least a perhaloolefin having two carbon atoms and vinyl acetate in the presence of a hydrocarbon emulsifier or in the absence of an emulsifier, provided that the hydrocarbon emulsifier excludes a compound (1) represented by the formula (1):
    [Chem. 1]

    wherein R 1 and R 2 are the same as or different from each other and each represent a C4 to 12 unfluorinated saturated hydrocarbon group; M represents an alkali metal, an ammonium salt, or an amine salt.
