Abstract
Omega-chlorosulfonyl perfluoroalkanesulfonates and omega-fluorosulfonyl perfluoroalkane sulfonates. These compounds can be used to prepare esters, amides, or latent catalysts for the polymerization of cationically-sensitive monomers. The .omega.-chlorosulfonyl perfluoroalkanesulfonates can be reacted with ethylenically unsaturated compounds to incorporate hydrophilic perfluoroalkanesulfonate groups into the ethylenically unsaturated compound.
