Cyclic anhydrides of sulfoperfluoroaliphaticcarboxylic acids and perfluoroaliphaticdisulfonic acids, amide derivatives thereof, a process for making the same, curable compositions containing such cyclic anhydrides or amide derivatives thereof and cationically-sensitive monomers, a process for using such cyclic anhydrides or amide derivatives thereof as catalysts for the cure of cationically-sensitive monomers, and perfluoroaliphaticdisulfonyl fluorides useful for preparing cyclic anhydrides of perfluoroaliphaticdisulfonic acids. |
