摘　　要：以4-(4-羟基苯基)-2,3-二氮杂萘酮、4,4′-双(4-三氟乙烯基氧基)联苯为原料,通过逐步聚合反应,合成含氟乙基醚杂萘联苯聚芳醚(PPFEE),并对PPFEE进行磺化改性,制备出磺化含氟乙基醚杂萘联苯聚芳醚(SPPFEE)。对聚合物的结构与性能进行表征,PPFEE特性黏度为1.03 dL/g,玻璃化转变温度为189℃,5%热失重温度(T)为358℃,具有优异的热性能;SPPFEE的离子交换容量在0.75~1.62 mmol/g之间,T高于252℃;PPFEE和SPPFEE可溶于二甲基亚砜、N-甲基吡咯烷酮和N,N-二甲基甲酰胺等溶剂。Poly(phthalazinone ether)s containing fluorinated ethyl ether moieties(PPFEE)were synthesized from 4-(4-hydroxyphenyl)-2,3-diazanonaphthalenoneand 4,4′-bis(4-trifluorovinyloxy)biphenyl by a step wise polymerization reaction,and sulfonated poly(phthalazinone ether)s containing fluorinated ethyl ether moieties(SPPFEE)were synthesized.The structures and properties of PPFEE and SPPFEE were characterized.The PPFEE hasintrinsic viscosity of 1.03 dL/g,glass transition temperatureof 189℃,5%thermal weight loss temperature(T)of 358℃,and thus the polymer has good thermal properties.The ion exchange capacity of the SPPFEE is in the range of 0.75~1.62 mmol/g,withthe 5%thermal weight loss temperatures above 252℃.The PPFEE and SPPFEE are soluble in dimethyl sulfoxide,N-methylpyrrolidone,and N,N-dimethylformamide.
