Abstract
Provided are an anion exchange resin being capable of producing an electrolyte membrane and the like, which have improved chemical properties (durability). For example, used is an anion exchange resin comprising a hydrophobic unit being composed of a plurality of divalent hydrophobic groups repeated via carbon-carbon bond, the divalent hydrophobic group having a plurality of aromatic rings which are connected to each other via a divalent fluorine-containing group; and a hydrophilic unit being composed of a plurality of hydrophilic groups repeated via carbon-carbon bond, the hydrophilic groups being composed of a plurality of aromatic rings which are connected to each other via a divalent hydrocarbon group and/or carbon-carbon bond, and the hydrophilic groups containing an anion exchange group-containing group including a quaternary ammonium salt having a piperidine ring, and wherein the hydrophobic unit and the hydrophilic unit are connected via carbon-carbon bond.
