Abstract
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.
