中文摘要	bisphenol monomer 4-carboxylphenyl hydroquinone (4c-ph) containing carboxyl groups was synthesized by diazotization reaction of p-aminobenzoic acid and 1,4-benzoquinone and subsequent reductive reaction. copolymerization of bisphenol a, 4c-ph, sodium 5,5'-carbonylbis(2-fluorobenzene-sulfonate) and 4,4'-difluorobenzophenone at various molar ratios through aromatic nucleophilic substitution reaction resulted in a new sulfonated poly(ether ether ketone) containing pendant carboxyl groups (c-speek). the structures of the monomer 4c-ph and copolymers were confirmed by ft-ir and h-1 nmr. flexible and transparent membranes with sulfonic and carboxylic acid groups as the proton conducting sites were prepared. the dependence of ion-exchange capacity (iec), water uptake, proton conductivity and methanol permeability on the degree of sulfonation has been studied.
