Functional trifluorovinyl monomers and their copolymerization with fluoroolefins Functional trifluorovinyl monomers, process for the copolymerization of trifluorovinyl monomers with fluoroolefins and use of these trifluorovinyl monomers in forming fluoroelastomers.
Copolymers resulting from this copolymerization process and process for crosslinking these copolymers.
Treatment of tetrafluoroethene (TFE) with diethylzinc in the presence of lithium iodide gave 1,1,2-trifluoro-1-butene in moderate yield. In the absence of lithium iodide, however, the nucleophilic ...

Two new olefins, CH2BrCHBrCH2CFCF2 and CH2ClCHClCH2CFCF2, have been prepared as precursors to fluoro β-sultones. The new fluorinated sultone, CH2ClCHClCH2CFCF2OSO2, was obtained (from the sulfonation of CH2ClCHClCH2CFCF2), along with its rearranged isomer, CH2ClCHClCH2CF(SO2F)C(O)F, and hydrolysis product, CH2ClCHClCH2CF(SO2F)C(O)OH.

The synthesis of novel perfluorovinyl monomers CF2CFC3H6S – Figure options1 bearing hydroxyl or carboxyl as Figure options end-groups from 1,1,2-trifluoro-1,4-pentadiene 2 is presented. They were obtained by radicaladdition of ω-hydroxy and carboxy mercaptans to 2. These addition reactions were performed either photochemically or in the presence of various radical initiators used at different temperatures
