Abstract

Curable fluoropolymer containing repeating units derived from VDF and TFE and at least one other fluorinated comonomer and further containing -CF 2 CH 2 I end groups and branching sites derived from one or more perfluorinated bisolefinic ether(s) used as modifier(s), wherein the one or more perfluorinated bisolefinic ether(s) used as modifier(s) correspond to the general formula: CF 2 =CF-(CF 2 ) n -O-(R f )-O-(CF 2 ) m -CF=CF 2 wherein n and m are independent from each other either 1 or 0 and wherein R f represents a perfluorinated linear or branched, cyclic or acyclic aliphatic or aromatic hydrocarbon residue that may be interrupted by one or more oxygen atoms and comprises up to 30 carbon atoms. Further provided are methods of making the curable fluoropolymers and for making an article containing the curable polymers.
