Abstract:
A binder composition for a secondary battery positive electrode contains a specific polymer. The specific polymer includes a nitrile group-containing monomer unit and a linear alkylene structural unit having a carbon number of 4 or more. The pH of an extract of the specific polymer that is obtained by a specific method is 5.5 or higher.
