## Abstract Poly(phenylene oxide)s were synthesized by the oxidative polymerization of 2‐phenyl phenol (PP) and 2‐allyl 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

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
