Abstract
A series of high sulfonated poly(ether ether ketone)s were prepared by copo lymerization of sodium 5,5 ' -carbonylbis (2-fluorobenzenesulfonate)(2),4,4 ' -difluorobenzophenone (1) and bisphenol A(3) in the presence of potassiu m carbonate in dimethylsulfoxide. The copolymers were characterized by IR a nd DSC, The influence of degree of sulfonation on the properties of copolym ers, such as component, thermal stability, solubility and filming ability, was studied.
