The present invention provides a polymer solid electrolyte excellent in thermal properties, physical properties and ion conductivity and being close to practical level; especially, a totally solid electrolyte and a composition for producing the same. A composition for polymer solid electrolyte includes a copolymer having repeating units represented by Formula (I):n n(wherein each of R 1 to R 3 independently represents a hydrogen atom or a C1-C10 hydrocarbon group; R 4a and R 4b independently represents a hydrogen atom or a methyl group; R 5 represents a hydrogen atom, a hydrocarbon group, an acyl group or a silyl group; and m is an integer of 1 to 100), and repeating units represented by Formula (II):n n(wherein each of R 6 and R 8 independently represents a hydrogen atom or a C1-C10 hydrocarbon group; R 9 represents an organic group having at lease one functional group selected from the group consisting of hydroxyl group, carboxyl group, epoxy group, acid anhydride group and amino group); and an electrolyte salt. |
