Highly fluorinated cotelomers having the structure F (TFE) w (VDF) x (HFP) y (TrFE) zI containing one or several tetrafluoroethylene (TFE), vinylidene fluoride (or 1, 1- difluoroethylene, VDF), hexafluoropropene (HFP) or trifluoroethylene (TrFE) base units were synthesized by thermal step-wise cotelomerization of these fluoroolefins with perfluoroalkyl iodides. 1H and 19F NMR allowed one to characterize these cotelomers and to assess the ...
