中文摘要	a series of novel side-chain-type sulfonated poly(arylene ether ketone)s with pendant carboxylic acid groups copolymers (c-spaeks) were synthesized by direct copolymerization of sodium 5,5'-carbonyl-bis(2-fluorobenzenesulfonate), 4,4'-difluorobenzophenone and 4,4'-bis(4-hydroxyphenyl) valeric acid (dpa). the expected structure of the sulfonated copolymers was confirmed by ft-ir and h-1 nmr. membranes with good thermal and mechanical stability could be obtained by solvent cast process. it should be noted that the proton conductivity of these copolymers with high sulfonation degree (ds > 0.6) was higher than 0.03 s cm(-1) and increased with increasing temperature. at 80 degrees c, the conductivity of c-spaek-3 (ds = 0.6) and c-spaek-4 (ds = 0.8) reached up to 0.12 and 0.16 s cm-1, respectively, which were higher than that of nafion 117 (0.10 s cm(-1)).
