POLYMER COMPOUND, INTERMEDIATE COMPOSITION, NEGATIVE ELECTRODE, ELECTRICITY STORAGE DEVICE, SLURRY FOR NEGATIVE ELECTRODES, METHOD FOR PRODUCING POLYMER COMPOUND, AND METHOD FOR PRODUCING NEGATIVE ELECTRODE

摘要

This polymer compound, which is used as a binder for negative electrodes of electricity storage devices, is obtained by condensation of a vinyl polymer that contains a carboxyl group and a third compound that is selected from among aromatic polyfunctional amines, phosphorous acid, phosphorous acid esters, trialkoxysilanes and phosphoric acid.
