Abstract: poly(arylene ether ketone) carring multi-sulfonated side chain was prepared via graft polymerization reaction. The obtained soluble sulfonated polymer SP-I and SP-II have high viscosity (ηinh >1.72dL/g). The transparence and tough sulfonated polymer film was obtained by solution casting method and exhibited good thermochemical stability, high proton conductivity(>0.90 S/cm)and good dimensional stability.

Key words: sulfonated poly(aryl ether ketone)s, proton exchange membranes, fuel cell
