Anion exchange resin, electrolyte membrane for fuel cell, binder for forming electrode catalyst layer, battery electrode catalyst layer and fuel cell

An anion exchange resin, comprising:

• 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, a divalent silicon-containing group, a divalent nitrogen-containing group, a divalent phosphorus-containing group, a divalent oxygen-containing group, a divalent sulfur-containing group, or carbon-carbon bond;
• 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, a divalent silicon-containing group, a divalent nitrogen-containing group, a divalent phosphorus-containing group, a divalent oxygen-containing group, a divalent sulfur-containing group, or carbon-carbon bond, the aromatic ring or at least one of the aromatic rings having an anion exchange group;
• and
• divalent fluorine-containing groups as shown in formula (11′);
• wherein the divalent hydrophobic groups are repeated via ether bond, thioether bond, or carbon-carbon bond to form a hydrophobic unit;
• wherein the divalent hydrophilic groups are repeated via ether bond, thioether bond, or carbon-carbon bond to form a hydrophilic unit;
• wherein the hydrophobic unit and the hydrophilic unit are bonded via ether bond, thioether bond, or carbon-carbon bond;
• and
• wherein the divalent fluorine-containing group as shown in formula (11′) is bonded via ether bond, thioether bond, a carbon-silicon bond, or carbon-carbon bond in the main chain or main chains of the hydrophobic unit and/or the hydrophilic unit
• wherein, I is an integer of 2 to 12.
