Abstract
Abstract An ion-conductive polymer electrolyte comprises an organic polymer, a soluble electrolyte salt and an organic solvent. The organic polymer is the compound obtained by crosslinking an organic compound having a structure of the following general formula 1; Z--[(A.sub.m --X.sub.p)--Y].sub.k 1 in which Z is a residue of a compound having at least one active hydrogen, Y is an active hydrogen group or polymerizable functional group, m is an integer of 1 to 250, k is an integer of 1 to 12, A is a structure of the following general formula 2; ##STR1## wherein n is an integer of 0 to 25, R is an alkyl, alkenyl, aryl or alkylaryl group having 1 to 20 carbon atoms, X is --(CH 2 --CH 2 --O)--, and p is 0 or an integer of 1 to 450, and, when p is not O, A and X are block-copolymerized, m shows the total number of copolymerized A units and p shows the total number of copolymerized X units.
