✦ Synopsis

Novel high molecular weight comb-shaped polyethers were synthesized and used as the matrix of a polymer solid electrolyte. Both the main chain and the side chain of these polyethers consist of oxyethylene units. The new polyethers possess Ðlm-forming properties, because the weight-average molecular weights were over 106. The short side chains of oxyethylene units gave rise to less crystallization of poly(oxyethylene) segments and to an increase of ionic conductivity when doped with lithium perchlorate.
