(1) a structural unit derived from a (meth) acrylate monomer (A) having a hydroxyl group, (2) a structural unit derived from a polyfunctional (meth) acrylate monomer (B), and (3) a reactive surfactant. A battery electrode binder containing a polymer containing a structural unit derived from (C) is disclosed. Using this binder, an electrode is produced to produce a battery such as a lithium ion secondary battery. Provided are a water-based binder having a high binding property and not causing oxidative deterioration particularly in an electrode environment and having a small environmental load, and an electrode and a battery using the same. |
