    Abstract: An anion exchange ionomer contains a fluorinated, ether-free backbone, and a fluorinated ether based quaternary ammonium functional group: said backbone comprises a copolymer of a polyarylene and a fully fluorinated alkyl hydrocarbon, said hydrocarbon unit having a fluorinated ether side group. Such a polymer is produced by reaction of an arylene unit with 2-bromo-1,1,2,2-tetrafluoroethylene trifluorovinyl ether in the presence of a strong acid. The novel polymer has improved chemical and mechanical stability as compared to the state-of-the-art materials for incorporation in anion exchange membrane.
