Disclosed is a fluorine-containing polymer aqueous dispersion in which a fluorine-containing polymer is dispersed using, as an emulsifier, a polyfluoroalkylphosphonic acid salt represented by the general formula: n C n F 2n+1 (CH 2 CF 2 ) a (CF 2 CF 2 ) b (CH 2 CH 2 ) c P(O)(OM 1 )(OM 2 ) [I],n n wherein M 1 is a hydrogen atom, an alkali metal, an ammonium base, or an organic amine base, M 2 is an alkali metal, an ammonium base, or an organic amine base, n is an integer of 1 to 6, a is an integer of 1 to 4, b is an integer of 1 to 3, and c is an integer of 1 to 3. This fluorine-containing polymer aqueous dispersion uses a polyfluoroalkylphosphonic acid salt with a low bioaccumulation potential as an emulsifier, and has excellent mechanical stability. |
