An oligo-polyether sulfate(SPEO) was prepared from polyethylene oxide and HClSO₃ and a series of solid polymer electorlytes, complex of oligo-polyether sulfate with polyether-polyurethane, were prepared using polydioxolane as a plasticizer. FT IR, ¹H NMR and complex impedance analysis were used to characterize the samples. The effects of temperature, salt concentration and plasticizer on the ionic conductivity of the complexes were investigated. The ionic conductivity was not of Arrhenius type in relation with temperature and it increased with increase of oligo polyether sulfate. At the same molar ratio of ether unit to Na⁺ the ionic conductivity of PU/SPEO600 was higher than that of PU/SPEO400. The highest ionic conductivity of the complexes was 10^-5 S/cm at 60℃. The plasticizer polydioxolane had great effect on the ionic conductivity.
