Abstract
The present invention provides an anion exchange resin capable of producing an electrolyte membrane for a fuel cell, a binder for forming an electrode catalyst layer and a battery electrode catalyst layer. The anion exchange resin of the present invention has a hydrophobic unit, a hydrophilic unit and divalent fluorine-containing groups. The hydrophobic unit has divalent hydrophobic groups composed of one aromatic ring or a plurality of aromatic rings that are repeated via carbon-carbon bond. The hydrophilic unit has divalent hydrophilic groups composed of one aromatic ring or a plurality of aromatic rings, at least one of which has an anion exchange group, that are repeated via carbon-carbon bond. The divalent fluorine-containing groups have a specific structure and are bonded via carbon-carbon bond to the hydrophobic unit and/or the hydrophilic unit and/or a moiety other than these units.
