ABSTRACT: Novel telechelic primary dihydroxyl and diacrylate cooligomers based on vinylidene fluoride (VDF) and perfluoromethyl vinyl ether (PMVE) were synthesized as precursors of original photo-cross-linkable networks. First, α,ω-diiodopoly(VDF-co-PMVE) copolymers were generated by iodine transfer copolymerization of VDF and PMVE controlled by 1,4-diiodoperfluorobutane chain transfer agent, leading to cooligomers with molecular weights ranging between 1,500 and 7,000 g·mol−1 with a narrow polydispersity (
