中文摘要 | a novel strategy in which the benzimidazole group and sulfonic group are simultaneously attached to an aromatic polymer has been reported in this paper. for this purpose, sulfonated poly(arylene ether ketone) copolymers containing carboxylic acid groups (spaek-x-cooh, x refers to the molar percentage of sulfonated repeating units) are prepared by the aromatic nucleophilic polycondensation of sodium 5,5'-carbonyl-bis(2-fluobenzene-sulfonate) (sdfbp), 4,4'-difluorobenzophenone (dfbp) and phenolphthalin (ppl). then the carboxylic acid groups attached to the spaek-x-cooh are transformed to benzimidazole units through condensation reactions (referred to as spaek-x-bi). fourier transform infrared spectroscopy and h-1 nmr measurements are used to characterize and confirm the structures of these copolymers. |
