| 摘要 |
The present invention provides a polymer, a polymer electrolyte and the use thereof. The polymer has, as a structural unit, a phenylene group in which two or three hydrogen atoms each have been substituted with a group represented by the following formula (A), and is insoluble in water:
wherein A 1 represents a group represented by formula (1a), formula (1b) or formula (1c) below, and the two or three A 1 groups may be the same as or different from each other,
wherein R 10 and R 11 each independently represents a hydrogen atom, an alkyl group of 1 to 20 carbon atoms, or an aryl group of 6 to 20 carbon atoms, R 12 represents a hydrogen atom, an alkyl group of 1 to 20 carbon atoms, or an aryl group of 6 to 20 carbon atoms, M represents a metal ion or an ammonium ion, and in a case where M represents a divalent or higher-valent metal ion, M may be further bonded to another substituent. |
