Abstract

Abstract: A novel series of sulfonated poly(arylene ether sulfone)s with various of sulfonation degrees were synthesized by nucleophilic displacement polycondensation of tert-butylhydroquione with different molar ratios of 4,4'-diflouorobenzophenone to 3,3'-disulfonate-4,4'-dichlorodiphenylsulfone in the presence of potassium carbonate in NMP.The structure and property of polymers were characterized and studied by FTIR,DSC and etc..They can be easily cast into tough membranes and show good mechanical and electrochemical properties.The polymers show good prospective usages in the proton exchange membranes fuel cell.

Key words: Sulfonation, PES, Proton exchange membrane, tert-Butylhydroquione
