Abstract: Aseries of high sulfonated poly(ether ether ketone)s were prepared by copolymerization of sodium 5,5'-carbonylbis(2-fluorobenzenesulfonate)(2), 4,4'-difluorobenzophenone(1) and bisphenol A(3) in the presence of potassium carbonate in dimethylsulfoxide. The copolymers were characterized by IRand DSC. The influence of degree of sulfonation on the properties of copolymers, such as component, thermal stability, solubility and filming ability, was studied.

Key words: Poly(ether ether ketone)s, Copolymerization, Sulfonation
