Abstract
Poly(phenylene oxide)s were synthesized by the oxidative polymerization of 2βphenyl phenol (PP) and 2βallyl phenol (AP). The copolymers were also synthesized with 80 mol % PP and 20 mol % AP and with equimolar monomers. The polymers were characterized. Blends of these polymers with poly(vinylidene fluoride) were prepared. These blend membranes were sulfonated, and their suitability for applications in fuel cells was evaluated.

A new, milder sulfonation process was used to produce ion-exchange polymers from a commercial polysulfone (PSU). Membranes obtained from the sulfonated polysulfone are potential substitutes for perfluorosulfonic acid membranes used now in polymer electrolyte fuel cells. Sulfonation levels from 20 to
