Poly(2-pyridone-3,5-diyl)s with -(CH2)(4)-SO3M (M = H or Na) side chains have been prepared by nickel-complex promoted dehalogenative polycondensation. A composite film of the polymer with -(CH2)(4)-SO3H side chains and poly(vinyl alcohol) showed a proton conductivity of 1.5 x 10(-1) S cm(-1) at 80 degrees C and 95% humidity. A copolymer with pyridine showed a high stability against oxidation by a Fenton reagent. (C) 2012 Elsevier Ltd. All rights reserved.
