Description	Diffusion coefficients of H+ and Na+ ions in sulphonated poly(2,6-dimethyl-1,4- phenylene oxide) (PPO) intermolecularly complexed with poly(2-butylaniline) (PBA) or poly-[2,2Ž-(m-phenylene)-5,5Ž-bibenzimidazole] (PBI) were evaluated from conductivity and H+/Na+ ion exchange measurements. Ion exchange capacity and transport properties of the PPO membranes with a degree of sulphonation higher than 29 % are comparable to those of Nafion. Intermolecular complexing of sulphonated PPO membrane was found to improve its mechanical and chemical stability. The observed deterioration of ion exchange capacity and ion transport with increasing content of the complexing agent is related to the partial occupation of the fixed sulpho- groups by the tertiary nitrogen groups present in the PBA and PBI.
