    Abstract: POLY (HYDROXYARYLPOLYMETHYLENESULFONIUM) SALTS (I), PREPARED BY CONDENSATION OF A POLYPHENOLIC RESIN WITH A CYCLIC SULFIDE, ARE CONVERTED INTO A SULFONIUM HYDROXIDE INNER SALT (II) A REACTIVE ZWITTERIONIC MONOMER. THESE ZWITTERIONIC MONOMERS THERMALLY POLYMERIZE TO YIELD WATER-INSOLUBLE, THERMOSET RESINS USEFUL AS ADHESIVES, COATINGS, FILMS, AND IMPREGNANTS. APPLIED TO NON-POROUS SURFACE, SUCH AS GLASS AND WIRE, HARD SURFACE COATINGS WITH HIGH IMPACT RESISTANCE COUPLER WITH GOOD WATER AND CHEMICAL RESISTANCE ARE OBTAINED.

    WHERE Z IS -CH2- AND $(X+Y)-1-20, ARE PREPARED BY CONDENSATION OF A POLYNUCLEAR PHENOL WITH A CYCLIC SULFIDE. THESE SALTS CAN BE CONVERTED INTO A CYCLIC SULFONIUM HYDROXIDE INNER SALT OR ZWITTERIONIC MONOMER (II). THESE REACTIVE CYCLIC SULFONIUM ZWITTERION MONOMERS THERMALLY POLYMERIZE TO YIELD WATER-INSOLUBLE, THERMOSET RESINS USEFUL AS ADHESIVES, COATINGS, FILMS, AND IMPREGNANTS.
