摘　　要：用 3 ,3’-二磺酸钠基 -4 ,4 -二氟二苯酮合成了具有高磺化度的荷电聚醚醚酮 .用红外吸收光谱及 DSC对其进行了表征 .研究了共聚物的组成、热稳定性、溶解性。A series 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 IR and DSC. The influence of degree of sulfonation on the properties of copolymers, such as component, thermal stability, solubility and filming ability, was studied.
