Fluoropolymer Comprising Pendent Groups with Ionic Bis(Sulfonyl)Imide Moiety and Perfluoroether Terminal Group

Fluoropolymer Comprising Pendent Groups with Ionic Bis(Sulfonyl)Imide Moiety and Perfluoroether Terminal Group

A fluoropolymer is described comprising pendent groups having the formula: -(CF2)a-(OCbF2b)c-(OCeF2e)-SO2-[NX2-SO2(CF2)f-SO2]d-NX1-SO2-Rf wherein Rf is a perfluoroether and X1 and X2 are independently cationic counterions. Also described are various articles including catalyst ink, polymer electroly...

description A fluoropolymer is described comprising pendent groups having the formula: -(CF2)a-(OCbF2b)c-(OCeF2e)-SO2-[NX2-SO2(CF2)f-SO2]d-NX1-SO2-Rf wherein Rf is a perfluoroether and X1 and X2 are independently cationic counterions. Also described are various articles including catalyst ink, polymer electrolyte membranes, and membrane electrode assemblies comprising the fluoropolymer described herein; as well as a method of making a fluoropolymer.
