Ion conduction of poly[methoxy oligo (oxyethylene) propylene] synthesized by the Et(Ind)(2)ZrCl2-MAO catalyst

Poly[methoxy oligo (oxyethylene) propylene] was synthesized by means of the Et(Ind)(2)ZrCl2-MAO catalyst. The ionic conductivity of poly[methoxy oligo (oxyethylene) propylene] with the lithium salt depends on the content of t he lithium salt. The temperature dependence of conductivity was determined and the Vogel-Tammann/Hesser-Fulcher (VTF) plot agreed well with theoretica l values, confirming the influence of the polymer segmental motion on condu ctivity. The ionic conductivity as high as 10(-4.7) s/cm can be obtained at room temperature, and this can be increased one or two orders of magnitude by blending the polyelectrolyte with hydroxyl-containing additives such as tetraethylene glycol.
