Abstract
A polymer compound is formed by condensing a polyacrylic acid having some of carboxyl groups converted into a lithium salt with a polyfunctional amine represented by the following general formula (1). A chain structure constituted by the polyacrylic acid has free carboxyl groups and carboxyl groups converted into a lithium salt. Y is a straight-chain alkyl group having 1 to 4 carbon atoms, a phenylene group, or an oxygen atom. R1 and R2 are each independently one or more hydrogen atoms, a methyl group, an ethyl group, a trifluoromethyl group, or a methoxy group.
