1. A process for applying TFEHFP copolymer to a conductor comprising:
(a) fluorinating TFEHFP copolymer in an extruder, and
(b) extruding said TFEHFP onto a conductor
wherein said fluorinating comprises
(i) melting said copolymer,
(ii) contacting said molten copolymer with fluorine in isolation from said melting, said contacting being carried out in a reaction zone having free volume,
(iii) subdividing molten copolymer in said reaction zone to enable said fluorine to effectively contact said molten copolymer so as to carry out the chemical reaction between said fluorine and said molten copolymer,
(iv) devolatilizing the resultant molten copolymer in isolation from (b) and (c), and
(v) cooling the devolatilized copolymer.
