    摘要: A polymeric solid electrolyte comprising a high molecular compound and a salt wherein the high molecular compound is a product formed by graft-polymerizing an alkylene oxide to the saponification product of a copolymer of ethylene with a vinyl ester of an aliphatic carboxylic acid. The polymeric solid electrolyte has a high ionic conductivity of 10.sup.-5 S/cm or more even at a temperature of 30.degree. C., shows a low temperature dependency of ionic conductivity and thus can be used as the solid electrolyte of various electrochemical devices such as batteries.
