Abstract
An object of the present disclosure is to provide a method for producing a fluorine-containing polymer and a composition containing the fluorine-containing polymer. The present disclosure provides a composition comprising (A) a fluorine-containing polymer comprising as a main component a structural unit containing a fluorine-containing aliphatic ring, and (B) an aprotic solvent, wherein the fluorine-containing aliphatic ring of the fluorine-containing polymer (A) contains one, two, or three etheric oxygen atoms as a ring-constituting atom; when the fluorine-containing aliphatic ring contains a plurality of etheric oxygen atoms, the etheric oxygen atoms are not adjacent to each other; and the fluorine-containing polymer (A) is present in an amount of 20 mass % or more based on the mass of the composition.
