Abstract

A binder for a nonaqueous electrolyte secondary battery electrode and use thereof are described. The binder contains a crosslinked polymer or salt thereof, the crosslinked polymer having an ethylenically unsaturated carboxylic acid and a crosslinkable monomer in constituent monomers thereof, or salt thereof, wherein the crosslinked polymer includes the ethylenically unsaturated carboxylic acid in an amount of 20 to 99.95 mass % of the total constituent monomers, and the crosslinked polymer includes at least one compound selected from the group made of trimethylolpropane diallyl ether and trimethylolpropane triallyl ether as the crosslinkable monomer.
