Abstract
Sulfonyl fluoride substituted .alpha.,.beta.,.beta.-trifluorostyrene monomers are disclosed. The monomers are incorporated into polymeric compositions which are conveniently hydrolyzed to produce polymeric compositions which include ion-exchange moieties. The resulting compositions which include ion-exchange moieties are particularly suitable for use as solid polymer electrolytes in electrochemical applications, such as, for example, electrochemical fuel cells.
Claims2
The compound p-sulfonyl fluoride-.alpha.,.beta.,.beta.-trifluorostyrene prepared by reacting a solution of p-iodobenzenesulfonyl fluoride with 1,2,2-trifluoroethenyl zinc bromide in the presence of a noble metal catalyst at an elevated temperature.
