Abstract

A polyether copolymer having a weight-average molecular weight of 10to 10, formed from 3 to 30% by mol of a repeating unit derived from propylene oxide, 96 to 69% by mol of a repeating unit derived from ethylene oxide, and 0.01 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.
