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.

A method for producing a fluorinated alicyclic structure-containing polymer which comprises contacting with fluorine gas a fluorinated alicyclic structure-containing polymer having an unstable terminal group derived from a polymerization initiator and/or a chain transfer agent, said polymer being dissolved in a fluorine-containing solvent when contacted with said fluorine gas, 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.
