摘要： A perfluorovinyl ether monomer represented by the following formula (1):
wherein: m is an integer of from 0 to 5; n is an integer of from 1 to 5; and each of R 1 and R 2 independently represents a hydrogen atom, an unsubstituted or substituted C 1 -C 10 hydrocarbon group, or a substituted silyl group, with the proviso that, when each of R 1 and R 2 is independently the hydrocarbon group or the substituted silyl group, R 1 and R 2 are optionally bonded together, thereby forming a ring. Also disclosed are a method for producing the perfluorovinyl ether monomer; a fluorinated polymer obtained from the monomer and a method for producing the same; a polymer film obtained from the polymer; a modified or crosslinked polymer film obtained from the polymer film; and a solid polymer electrolyte membrane obtained from the modified or crosslinked polymer film.

摘要： A membrane/electrode assembly for solid polymer fuel cells is disclosed wherein a fluorinated sulfonic acid polymer having a monomer unit represented by the following general formula (3): (3) (wherein, Rf1 represents a divalent perfluorohydrocarbon group having 4-10 carbon atoms) is used for at least one of the membrane and the catalyst binder. The fluorinated sulfonic acid polymer has a melt flow rate (MFR) of not more than 100 g/10min at 270˚C when the -SO3H group in the polymer is changed into -SO2F.
