Method for producing aqueous fluorinated polymer dispersion, aqueous fluorinated polymer dispersion and fluorinated polymer

Abstract

To provide a method for producing a stable aqueous fluorinated polymer dispersion in which a fluorinated polymer having a high molecular weight is dispersed with excellent productivity, and an aqueous fluorinated polymer dispersion and a fluorinated polymer obtained by the production method. A method for producing an aqueous fluorinated polymer dispersion, which comprises subjecting a monomer containing at least one fluorinated monomer to emulsion polymerization in the presence of a hydrocarbon anionic emulsifier having a critical micelle concentration of at most 0.09 mass % in an aqueous medium to produce an aqueous dispersion of a fluorinated polymer.
