Abstract
A polyether copolymer prepared from 5 to 95% by mol of a monomer of the formula (I), 95 to 5% by mol of a monomer of the formula (II) and 0 to 15% by mol of a monomer of the formula (III) or (IV) as a crosslinking component; the copolymer having a weight-average molecular weight within the range from 10.sup.3 to 10.sup.7 : ##STR1## The copolymer of the present invention provides a polymer solid electrolyte having such a feature that it is superior in ionic conductivity and also superior in processability, moldability, mechanical strength and flexibility to a conventional solid electrolyte.
