PURPOSE:To stabilize the subject polymer at a low cost by irradiating light with a specified wave length on powder or moldings of a perfluoro polymer having unstable terminal groups and capable of melt processing in an atmosphere of gaseous fluorine for fluorination thereof at the room temperatures under the atmospheric pressure. CONSTITUTION:On powder or moldings of a perfluoro polymer [e.g. (co)polymer of tetrafluoroethylene, hexafluoropropylene, etc.] having unstable terminal groups and capable of melt processing, light (preferably mercury vapor lamp or xenon lamp as the light source) with 150-700nm wave length is irradiated in an atmosphere of gaseous fluorine. |
