PROBLEM TO BE SOLVED: To provide a polymer, excellent in adhesion and binding property, used as a binder for an electrode of a power storage apparatus, soluble to an organic solvent such as N-methyl-2-pyrrolidone (NMP), excellent in dispersibility of a conductive assistant .SOLUTION: A main chain composed of a polymer of an acid monomer having a carboxyl group is included. At a part of side chains, an alkyl group is bonded to a carbonyl group. The alkyl group makes it possible to improve compatibility with an organic solvent and improve dispersibility of a conductive assistant. |
