heal.abstract	Oxyethylene-alkylaromatic polyionenes were studied in the 10(-2) to 10(6) Hz frequency range and in the -120 to +80degreesC temperature range using dielectric spectroscopy. Dielectric spectra at low temperatures disc played dipole polarization relaxation due to a local motion of polymer chains, whereas the contribution of electric conduction prevailed at elevated temperatures. Plots of the direct-current conductivity against the reciprocal temperature followed the Arrhenius law with an activation energy of 1-1.5 eV, which is not typical of polymeric electrolytes and indicates that the conductivity is thermally activated. The hi-h conductivity of the polymers at T much less than T-g is due to their structure, which resembles the structure of an inorganic glass with ionic sites dissolved in an ordered matrix.	en
