Abstract
A binder composition for a non-aqueous secondary battery contains water-soluble macromolecules, water, and a particulate polymer formed of a polymer that includes a block region formed of an aromatic vinyl monomer unit. Surface acid content A of the particulate polymer is 0.05 mmol/g or more, acid content B in an aqueous phase of the binder composition per 1 g of the particulate polymer is not less than 0.03 mmol/g and not more than 0.80 mmol/g, and a ratio (A/B) of the surface acid content A of the particulate polymer and the acid content B in the aqueous phase of the binder composition is not less than 0.5 and not more than 5.0.
