Anion exchange membrane, process for its production and solution treating apparatus

摘要

An anion exchange membrane comprising a resin phase which contains from 20 to 96 mass % of a polymer having repeating units represented by the following formula (1): wherein A is a C_3-8 alkylene group or an alkyleneoxyalkyl group having a total carbon number of from 4 to 9, each of R¹, R² and R³ is a hydrogen atom, a C_1-6 alkyl group or a hydroxyalkyl group, and X^- is an anion, and wherein any hydrogen atom bonded to the benzene ring may be substituted by an alkyl group or a halogen atom, and from 4 to 80 mass % of a thermoplastic polymer having no ion exchange groups, substantially uniformly.
