Due to its potential in fuel cell applications, the synthesis of sulfonated polyphenylsulfone has been optimized with an ion exchange capacity (IEC)(sPPS-360) of 2.78 mequiv g -1, the effect of increasing molecular weight on mechanical properties was also investigated. The synthesis involves the stepwise polymerization of sulfonated difluorodiphenyl sulfone (sDFDPS) with thiobisbenzenethiol (TBBT), followed by oxidation (by hydrogen peroxide). In the past, this procedure was characterized by very low reproducibility and generally limited achievable molecular weights. Sodium sulfate, a by-product in the preparation of sDFDPS, was found to be retained throughout the established purification of the monomer by recrystallization from an alcohol/water mixture. Pollution was quantified by atomic absorption spectroscopy (AAS) and combustion analysis. At the corrected monomer ratio,M n 15-30 kDa to 154 kDa). The optimized sPPS-360 significantly improved viscoelasticity, better film forming properties and reduced water absorption (when immersed in water) in the tensile test at 30% RH.
