✦ Synopsis


Ahatract~hain-extended comb-like polyepoxides (PEP) with oligoethylene oxide units in the side chains have been synthesized and complexed with LiClO, to obtain a new class of polymer electrolyte. PEP/Li complexes showed conductivity up to 10T4S cm-' at room temperature. The influence of thermal properties, side chain length, content of diepoxide and salt concentration on conductivity was investigated. Finally the comparison between PEP/Li systems and similar polyvinylethers (PVE/Li) based membranes showed a significant improvement in conductivity with the polyepoxide structure in spite of negligible differences in complexes' Ts.

This work reports the synthesis and characterisation of two new electrolytes based on polyethers (PEO and PPO) and polyphosphazene (PPz). In the structural study, the existence of new crystalline phases becomes apparent as a consequence of the co-ordination of the lithium salt (lithium triflate) and

Several polyacetals have been investigated as host polymer, for polymer electrolytes. The cationic polymerization and copolymerixation of dioxolane @XL) and 4-methyl, dioxolane (MDXL) are reported. If PDXL is a semi-crystalline polymer, an amorphous polymer electrolyte at room temperature is obtaine
