摘要： Provided are an anion exchange resin being capable of producing an electrolyte membrane, a binder for forming an electrode catalyst layer and a battery electrode catalyst layer, which have improved electrical properties and chemical properties. For example, used is an anion exchange resin which has a hydrophobic unit being composed of bisphenol AF residues repeated via carbon-carbon bond and a hydrophilic unit being composed of hydrophilic groups repeated via carbon-carbon bond, in which the hydrophilic group is formed by connecting an anion exchange group to a fluorene backbone via a divalent saturated hydrocarbon group, and in which the hydrophobic unit and the hydrophilic unit are connected via carbon-carbon bond.

摘要： 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.
