Title: Ar-cyclic sulfonium arenethiol salts and their zwitterions

Abstract: Ar-cyclic sulfonium arenethiol salts exemplified by the formula: ##STR1## may be converted to their corresponding zwitterion, exemplified by the formula: ##STR2## The latter polymerize very readily upon exposure to mild conditions of heat or radiative energy. The resultant polymers are water-insoluble resins useful as adhesives, coatings, films and the like. The zwitterions containing more than one arenesulfide and cyclic sulfonium group per molecule, crosslink upon exposure to heat to form thermoset resins.
