Abstract:
An anion exchange resin having a hydrophobic unit with divalent hydrophobic groups bonded to each other via an ether bond, the divalent hydrophobic groups being composed of one aromatic ring, or being composed of a plurality of aromatic rings which are bonded to each other via a divalent hydrocarbon group, carbon-carbon bond or the like; and a hydrophilic unit having divalent hydrophilic groups bonded to each other via carbon-carbon bond, the divalent hydrophilic groups being composed of one aromatic ring, or being composed of a plurality of aromatic rings which are bonded to each other via a divalent hydrocarbon group or carbon-carbon bond, the aromatic ring or at least one of the aromatic rings having an anion exchange group are bonded via carbon-carbon bond.
