摘要：

Biaryl hydroxy polymers with orthogonal disposition of proton transporting ?OH moieties have been synthesized via conventional free radical polymerization. The polymers are characterized for their thermal stability and proton conductivity, and the results are compared with the corresponding styrenic hydroxy polymers. The orthogonal disposition of ?OH moieties in biaryl polymers does result in lower Ea for proton transport. However, the lower Ea values in biaryl polymers did not translate into a net increase in proton conductivity. (c) 2011 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2012
