Abstract: Provided is a binder composition for a non-aqueous secondary battery electrode with which it is possible to form a slurry composition for a non-aqueous secondary battery electrode having excellent stability and an electrode for a non-aqueous secondary battery having excellent peel strength after thermal drying. The binder composition for a non-aqueous secondary battery electrode contains a particulate polymer A and a particulate polymer B. The particulate polymer A includes: a backbone portion formed of a block copolymer that includes an aromatic vinyl monomer unit and an aliphatic conjugated diene monomer unit; and a graft portion. The particulate polymer B includes an aliphatic conjugated diene monomer unit in a proportion of 70.0 mass % or more and includes a graft portion.

Abstract: A binder composition for a non-aqueous secondary battery contains a particulate polymer including a block copolymer A represented by the following general formula (A): Ar1a-Da-Ar2a. (In general formula (A), Ar1a indicates a block region that has a weight-average molecular weight of 5,500 to 20,000 and is formed of an aromatic vinyl monomer unit, Ar2a indicates a block region that has a weight-average molecular weight of 40,000 to 400,000 and is formed of an aromatic vinyl monomer unit, and Da indicates a block region that is formed of an aliphatic conjugated diene monomer unit.)
