Poly(hydroxyarylpolymethylenesulfonium)zwitterionic monomers and surface coatings therefrom
Abstract
Abstract POLY(HYDROXYARYLPOLYMETHYLENESULFONIUM) SALTS OF FORMULA I: (((-CH2-A-(B)C-CH2-)>S(+)-),R,(R'')A,HO-PHENYL)-(Z-((R'')A, HO-PHENYLENE))X-(Z-((R'')A,((-CH2-A-(B)C-CH2-)>S(+)-),HO- PHENYLENE))Y-R (X(-))2 WHERE Z IS -C(C1-C4 ALKYL)2- AND $(X+Y)=1, 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 MOMOMERS THERMALLY POLYMERIZE TO YIELD WATER-INSOLUBLE, THERMOSET RESINS USEFUL AS ADHESIVES, COATINGS, FILMS, AND IMPREGNANTS. APPLIED TO NONPOROUS SURFACES, SUCH AS GLASS AND WIRE, HARD SURFACE COATINGS WITH HIGH IMPACT RESISTANCE COUPLED WITH GOOD WATER AND CHEMICAL RESISTANCE ARE OBTAINED.
