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、成膜性及磺化度对共聚物性能的影响.

关键词: 聚醚醚酮, 共聚物, 磺化

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
