Abstract: | High molecular weight polymers have been prepared by ring-opening polymerization of propylene oxide PO using a Vandenberg initiator. Polymer electrolytes based on this polymer and an imide salt LiTFSI have been investigated. We present the results concerning the synthesis of the polymer and the glass transition temperatures evolution of the complexes with respect to salt composition. Diffusion constants of 19F and 7Li nuclei are determined by NMR techniques and a value of the cationic transport number t+ = 0.1 is obtained. |
