ABSTRACT:
Terpolymers of tetrafluoroethylene, hexafluoropropylene and either perfluoro(propyl vinyl ether) or perfluoro(ethyl vinyl ether) are described which are prepared by polymerizing the monomers in the presence of a chlorofluoroalkane or chlorofluorohydroalkane solvent and a chain transfer agent and an initiator in either an aqueous or nonaqueous medium. The terpolymers are useful as films, fibers or tubes.
