. The polymers are useful in an alkali-chloride electrolysis process, as a separator in an electrochemical preparation of inorganic and organic compounds, as a separator between an aqueous and an organic phase, or as a catalyst for Diels-Alder additions, Friedel-Craft reactions, aldol condensations, cationic polymerizations, esterifications, and acetal formations.
