Patent

CA 2221813

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.

L'invention porte sur des monomères de trifluorostyrène .alpha.,.beta.,.beta.substitués par du fluorure de sulfuryle. On incorpore ces monomères à des compositions polymères aisément hydrolysées de façon à produire des compositions polymères comprenant des fractions échangeuses d'ions. Les compositions ainsi obtenues, comprenant des fractions échangeuses d'ions, se révèlent des plus utiles en tant qu'électrolytes polymères solides dans des applications en électrochimiques, par exemple dans le cas de cellules de piles électrochimiques.
