Beschreibung
Zusammenfassung:	The invention is a sulfonic fluoropolymer having a fluoropolymer backbone having pendant groups attached thereto and represented by the general formula: ZSO2-(CF2)a-(CFRf)b-O- where: Z is selected from a halogen, an alkali metal, hydrogen, or OR; R is a branched or linear alkyl radical having from 1 to 10 carbon atoms or an aryl radical; a is 0-2; b is 0-2; provided a + b is not equal to 0; Rf is selected from -F, -Cl, perfluoroalkyl radials having from 1 to 10 carbon atoms and fluorochloroalkyl radicals having from 1 to 10 carbon atoms, wherein the sulfonic fluoropolymer has an equivalent weight of less than 800, and a hydration product of less than 29,000.
