Abstract:New poly(arylene ethers) containing side sulfo groups have been synthesized through the copolycondensation of 3,5-dinitrodiphenyl sulfone 4′-sulfonic acid and 4,4′-dichlorodiphenyl sulfone with bicyclic aromatic bisphenols under the conditions of aromatic nucleophilic substitution. On the basis of the blends of these copolymers with sulfonated poly(arylene ester ether ketone), membranes with satisfactory mechanical characteristics and high proton conductivity have been prepared.
