Abstract
Provided is a binder composition for a non-aqueous secondary battery with which it is possible to form a slurry composition for a non-aqueous secondary battery functional layer having excellent viscosity stability and a functional layer for a non-aqueous secondary battery having excellent pressability. The binder composition for a non-aqueous secondary battery contains water and a particulate polymer formed by a polymer including a block region composed of an aromatic vinyl monomer unit. The particulate polymer has a surface acid content of not less than 0.05 mmol/g and not more than 0.9 mmol/g.
