    • The present invention provides a fluoropolymer that is melt- processible and thermoplastic and that has a melting point between 100 °C and 320 °C. The fluoropolymer is derived from (a) one or more gaseous fluorinated monomers, (b) one or more modifiers selected from (i) olefins having a bromine or iodine atom bonded to a carbon of the double bond of the olefin, (ii) olefins corresponding to formula (I): Xa 2C = CXa-Rf-Br wherein each Xaindependently represents hydrogen, fluorine, bromine, chlorine or iodine, Rf is a perfluoroalkylene group, typically having 1 to 8 carbon atoms, a perfluorooxyalkylene group or a perfluoropolyether group and (iii) mixtures thereof; and (c) optionally one or more comonomers selected from non-gaseous fluorinated monomers and non-fluorinated monomers. The resulting fluoropolymer has long chain branches. The invention further provides a method for making these polymers.
