Abstract

Abstract An ion-conductive polymer electrolyte comprises an organic polymer and a soluble electrolyte salt. The organic polymer is obtained by crosslinking an organic compound having an average molecular weight of 1,000 to 20,000 and having a structure of the following formula ①; in which Z is a residue of a compound having at least one active hydrogen, R' is represented by the following formula ②; wherein n is 0 or an integer of 1 to 25, R is an alkyl, alkenyl, aryl or alkylaryl group having 1 to 20 carbon atoms; R 2 is an alkylene having not less than 2 carbon atoms, Y is a hydrogen atom or a polymerizable functional group, k is an integer of 1 to 12, ℓ is an integer of 1 to 230, m is an integer of 1 to 300, and ℓ/(ℓ + m) ≧ 0.1.
