Perfluorinated Ionomer Membranes

The past 15 years have witnessed an explosive growth in the literature on ionomers, i.e. ion-containing copolymers in which up to 15 mol % of the repeat units contain ionic groups. Two monographs have appeared on the subject(1,2), as well as proceedings of several symposia(3), in addition to a large number of individual publications and patents. Furthermore, Chemical Abstracts has started to issue, as part of their "CA Selects", the series entitled "Ion-Containing Polymers" ca. 2 years ago, and a biennial Gordon Conference on this topic started in 1979.
