Summary: | Provided is a method for producing a fluoropolymer, comprising polymerizing a monomer (I) represented by the general formula (I) in an aqueous medium to produce the fluoropolymer of the monomer (I), wherein an oxygen concentration in a reaction system of the polymerization is maintained at 500 ppm by volume or less: General formula (I): CX2=CY-CF2-O-Rf-Awherein X and Y are independently H, F, CH3, or CF3, and at least one of X and Y is F; Rf is a fluorine-containing alkylene group having 1 to 40 carbon atoms, or a fluorine-containing alkylene group having 2 to 100 carbon atoms and having an ether bond; and A is -COOM, -SO3M, -OSO3M, or - C(CF3)2OM, wherein M is H, a metal atom, NR74, imidazolium optionally having a substituent, pyridinium optionally having a substituent, or phosphonium optionally having a substituent, and R7 is H or an organic group. |
