Abstract
A method for producing a fluorinated alicyclic structure-containing polymer, which comprises contacting a fluorinated alicyclic structure-containing polymer having an unstable terminal group derived from a polymerization initiator and/or a chain transfer agent with fluorine gas in a fluorine-containing solvent, to convert the unstable terminal group to a stable terminal group and thereby to obtain a fluorinated alicyclic structure-containing polymer having substantially no unstable terminal group.
