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.
