coupling with sulfonated phenyl bromides was developed for the preparation of aromatic ionomers. Superacidic fluoroalkyl sulfonic acid and less acidic aryl and alkyl sulfonic acids were efficiently incorporated into the aromatic ring of model polystyrene, and the resulting sulfonatedionomers were characterized for their properties as proton-conducting membranes. The membrane properties of ionomers containing
