合成了一种磺化基在侧链上的聚芳醚.由于特殊单体结构的设计,磺化反应仅发生在聚合物的侧链上.这些磺化聚很容易溶于常见的有机溶剂,能够用溶液浇膜法制备光滑,坚韧的膜.通过Fenton's试剂和沸水测试表明,这种膜具有高的抗水解性和抗氧化性.%Novel poly(arylene ether)s with sulfonic acid groups attached to pendent biphenyl rings were successfully synthesized. The sulfonation took place only on the pendent biphenyl rings due to the special designed molecular structure. The sulfonated polymers were very soluble in common organic solvents and can be readily cast into tough and smooth films. The membranes cast from the sulfonated polymers showed excellent stabilities resistance to both oxidation and hydrolysis, as evidenced by subjecting to both Fenton's reagent test and immersion in boiling water.
