用磺化二氟二苯酮、二氟二苯酮与苯并咪唑双酚进行亲核共聚,合成了一系列具有不同磺化度的磺化(聚醚醚酮—苯并咪唑),用FTIR确认了其结构.聚物膜的水解和热稳定性测试结果表明,SPEEK-BI膜具有优异的热稳定性和水解稳定性.
Abstract：A series of sulfonated poly(eterh ether ketone-poly benzimidzole)s were prepared by copolymerization of sodium 5,5'-carbonylbis(2-fluorobenzenesulfonate)(SDFK),4,4'-difluorobenphenone(DFK) and 5,5'-Bis[2-(4-hydroxyphenyl)benzimidazole](HPBI) in the presence of postassium carbonate in dimethylsulfoxide.The chemical structures of copolymers were characterized by FTIR.The polymer electrolyte membrannes showed excellent themal stability both in air and nitrogen atmosphare,and good hydrolysis resistance in NaOH aqueous solution.
