Abstract
THE SYNTHESIS OF PERFLUORINATED VINYL MONOMERS AND THE FABRICATION OF PERFLUORINATED IONOMER MEMBRANES ARE PROPOSED. THE SYNTHESIS OF TRIFLUOROVINYL SULFONYL CHLORIDE THROUGH A 3-STEP REACTION IS PROPOSED. ALTERNATIVELY, THE SYNTHESIS OF OF TRIFLUOROVINYL SULFONYL FLUORIDE IS ALSO PROPOSED AS THE ACTIVE MONOMER FOR RADIATION GRAFTING. POLYTETRAFLUOROETHYLENE (TEFLON) WILL BE USED AS THE SUBSTRATE. BOTH ELECTRON RADIATION (B) AND GAMMA RADIATION CAN BE EMPLOYED AS THE IRRADIATION SOURCE FOR GRAFTING. THE RESULTING GRAFTED MEMBRANE CAN BE EASILY CONVERTED TO A PERFLUORINATED IONOMER MEMBRANE BY HYDROLYSIS. SOME SPECIFIC INDUSTRIAL APPLICATIONS ARE GIVEN.
