Abstract
Owing to the stability of the sulfonyl fluoride group and the reactivity of the amino group, aminobenzenesulfonyl fluorides enable the synthesis of a large number of polymers and copolymers bearing sulfonic acid groups. It is indeed possible to react aminobenzenesulfonyl fluorides with acrylic or methacrylic acid chloride or with vinyl isocyanate to obtain substituted acrylamides or vinylureas which can be polymerized or copolymerized with other vinyl monomers. Another method of preparing arylsulfonic polymers with the use of aminobenzenesulfonyl fluorides is the reaction of the latter with polymers containing reactive groups, such as polyacrylic anhydride and copolymers of maleic anhydride. The fluorosulfonyl-substituted polymers and copolymers can easily be hydrolyzed in slightly alkaline medium.
