Abstract:
1. A polymer electrolyte prepared by curing a polyimide, the polyimide comprising: a repeating unit of  and a reactive blocking group derived from a monoamine compound or monoanhydride compound having at least one carbon-carbon double bond at a terminal or at both terminals: wherein X is Y is X1, X2, X3, X4, X5, X6, X7, X8, Y1, Y2, Y3, Y4, Y5, Y6, Y7, and Y8 are independently selected from the group consisting of a hydrogen, a halogen, a C1-C30 alkyl group and alkyl halide group, and a C6-C30 aryl group and aryl halide group; Q is a chemical bond or a group selected from the group consisting of —O—, —CO—, —SO2-, —S—, -(T)a-, —(OT)a-, -(TO)a-, and —(OTO)a- (where T is an alkylene group substituted with at least one selected from a halogen and a C1-C10 alkyl halide group or an arylene group substituted with at least one selected from a halogen and a C1-C10 alkyl halide group, a is an integer in the range of 1 to 10); R1 and R2 are independently H or a monovalent organic group of  with the proviso that R1 and R2 are not both H; m is an integer in the range of 10 to 1000; and n is an integer in the range of 1 to 5.
