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.

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 for a fuel cell, a binder for forming an electrode catalyst layer and a fuel cell electrode catalyst layer, which have an improved physical property (anion conductivity); a method for producing thereof; an electrolyte membrane for a fuel cell, a binder for forming an electrode catalyst layer and a fuel cell electrode catalyst layer produced from the anion exchange resin; and a fuel cell having the electrolyte membrane or the electrode catalyst layer.
For example, the anion exchange resin is obtained by reacting a hydrophobic monomer with an aminoalkyl group-containing monomer, in which the hydrophobic monomer is composed of one aromatic ring or a plurality of aromatic rings to which two halogen atoms are bonded, and the aminoalkyl group-containing monomer is composed of one aromatic ring or a plurality of aromatic rings to which two halogen atoms are bonded and an aminoalkyl group is introduced; and by quaternizing the amino group. In the anion exchange resin, a divalent hydrophobic group formed by the residue of the hydrophobic monomer, and a divalent hydrophilic group formed by the residue of the quaternized aminoalkyl group-containing monomer are bonded via direct bond.-

摘要： 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.
