Abstract:
1. A composition for a polymer solid electrolyte comprising a copolymer having repeating units represented by Formula (I): wherein each of R 1 to R 3 independently represents a hydrogen atom or a C1-C10 hydrocarbon group; R 1 and R 3 may bond to one another to form a ring; each of 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; m is an integer of 1 to 100, and each of R 4a and each of R 4b may be the same or different when m is 2 or more; and repeating units represented by Formula (II): wherein each of R 6 and R 8 independently represents a hydrogen atom or a C1-C10 hydrocarbon group; R 6 and R 8 may bond to one another to form a ring; R 7 represents a hydrogen atom, a C1-C10 hydrocarbon group, a hydroxyl group, a hydrocarbonoxy group, a carboxyl group, an acid anhydride group, an amino group, an ester group, or an organic group having at least one functional group selected from the group consisting of hydroxyl group, carboxyl group, three-membered-ring epoxy group, acid anhydride group and amino group; and R 9 represents an organic group having at least one functional group selected from the group consisting of hydroxyl group, carboxyl group, three-membered-ring epoxy group, acid anhydride group and amino group; and an electrolyte salt, wherein the copolymer forms a microphase-separated structure, wherein the copolymer having the repeating units represented by the Formula (I) and the Formula (II) is a copolymer having an arrangement of block chains in an order of B1, C1, A, C2, and B2, wherein the block chain A has the repeating unit represented by the Formula (I); the block chain B1 has the repeating unit represented by the Formula (II), the block chain B2 has the repeating unit represented by the Formula (II) which may be the same or different from B1; the block chain C1 has a repeating unit represented by the Formula (III) wherein each of R10 to R12 independently represents a hydrogen atom or a C1-C10 hydrocarbon group, and R13 represents an aryl group or a heteroaryl group; and the block chain C2 has a repeating unit represented by the Formula (III) which may be the same or different from C1.
