Abstract
A polyether copolymer having a weight-average molecular weight of 10.sup.4 to 10.sup.7, comprising 5 to 40% by mol of a repeating unit derived from epichlorohydrin, 95 to 60% by mol of a repeating unit derived from ethylene oxide, and 0.001 to 15% by mol of a crosslinkable repeating unit derived from a reactive oxirane compound, gives a provide a crosslinked solid polymer electrolyte which is superior in processability, moldability, mechanical strength, flexibility and heat resistance, and has markedly improved ionic conductivity.
