Abstract
A method of producing a fluorine-containing polymer, containing conducting an addition polymerization of a fluorine-containing compound having 2 or more terminal fluorine-containing vinyl groups each directly bonded to an oxygen atom per molecule, and a compound having 2 or more groups represented by —XH, where X represents an oxygen atom or a sulfur atom; and a fluorine-containing polymer comprising a repeating unit represented by formula (i):wherein Rf1 represents a perfluoroalkylene group; each of Rf2 and Rf3 independently represents a fluorine atom, a perfluoroalkyl group or a perfluoroalkoxy group; at least two among Rf1, Rf2 and Rf3 may bond to each other to form a ring structure; X represents an oxygen atom or a sulfur atom; and L represents a divalent organic group.
