Anion exchange resin, method for producing thereof, electrolyte membrane for fuel cell, binder for forming electrode catalyst layer, fuel cell electrode catalyst layer and fuel cell

A method for producing an anion exchange resin, comprising:

• (A) preparing a hydrophobic monomer or a hydrophobic oligomer,
• wherein the hydrophobic monomer is composed of one aromatic ring, or is 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 a carbon-carbon bond, and wherein the aromatic ring(s) are substituted with two halogen atoms, pseudohalides or boronate groups;
• and
• wherein the hydrophobic oligomer is 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 a carbon-carbon bond, wherein the plurality of aromatic rings are bonded repeatedly 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 a carbon-carbon bond, and wherein the aromatic rings are substituted at both terminals with two halogen atoms, pseudohalides or boronate groups;
• (B) preparing an aminoalkyl group-containing monomer,
• wherein the aminoalkyl group-containing monomer is composed of one aromatic ring, or is 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 a carbon-carbon bond, and wherein the aromatic ring(s) are substituted with two halogen atoms, pseudohalides or boronate groups, and wherein at least one aromatic ring has an aminoalkyl group;
• (C) reacting the hydrophobic monomer or the hydrophobic oligomer with the aminoalkyl group-containing monomer to synthesize a polymer;
• and
• (D) quaternizing the amino group in the polymer;
• in the anion exchange resin,
• wherein the residue of the hydrophobic monomer or the hydrophobic oligomer forms a divalent hydrophobic group;
• wherein the quaternized amino group forms an anion exchange group;
• wherein the residue of the quaternized aminoalkyl group-containing monomer forms a divalent hydrophilic group;
• and
• wherein the divalent hydrophobic group and the divalent hydrophilic group are bonded via a carbon-carbon bond.
