Aromatic perfluorovinyl ether

In 2000, Ford et al. [103] reported the synthesis of aromatic perfluorovinyl ether monomers containing sulfonamide and the sulfonic acid functionality for different apphcations, such as PEMFCs [105]. As in the former example. Ford et al. used... 

FIG. 2.21 Synthesis of new aromatic perfluorovinyl ether monomers containing phosphonic acid functionality [99]. 

Using the optimal conditions for the radical terpolymerization of 4-[(a,/ ,/ -trifluorovinyl)oxy]bromobenzene with the fluoroalkenes, these authors reported the synthesis of new polymer electrolyte membranes based on fluoropolymers incorporating aromatic perfluorovinyl ether sulfonic acids [85,107]. In fact, a novel synthetic route for the preparation of perfluorovinyl ether monomer containing sulfonic functionalities, 4-[(a,, -trifluorovinyl)oxy]benzenesulfonic acid (TFVOBSA), was proposed. This monomer was synthesized in 72% overall yield. Further, the radical (co)- and terpolymerization of 4-[(a,, -trifluorovinyl)oxy] benzenesulfonyl chloride (TFVOBSC) with VDF, HFP, and PMVE (Fig. 2.25)...
