Abstract
To provide an anion exchange resin which has an anion exchange group having high alkali resistance and in which a main chain structure is not affected even if the anion exchange group decomposes. The anion exchange resin according to the present invention is characterized by having an imidazolium group as an anion exchange group in a side chain.
Claims17
An anion exchange resin comprising a side chain shown by a below formula (1)
- In the formula (1), R1, R2, R3, R4, R7, R8, and R9 each represents a hydrogen atom, an alkyl group which may contain a substituent group, a cycloalkyl group which may contain a substituent group, an aryl group which may contain a substituent group, or a group which bonds with a main chain forming the anion exchange resin;
- R5 and R6 each represents an alkyl group which may contain a substituent group, a cycloalkyl group which may contain a substituent group, an aryl group which may contain a substituent group, or a group which bonds with the main chain forming the anion exchange resin;
