BINDER COMPOSITION FOR NON-AQUEOUS SECONDARY BATTERY ELECTRODE, SLURRY COMPOSITION FOR NON-AQUEOUS SECONDARY BATTERY ELECTRODE, ELECTRODE FOR NON-AQUEOUS SECONDARY BATTERY, AND NON-AQUEOUS SECONDARY BATTERY

A binder composition for a non-aqueous secondary battery electrode contains a particulate polymer A and a particulate polymer B. The particulate polymer A is a block copolymer including an aromatic vinyl monomer unit and an aliphatic conjugated diene monomer unit having a carbon number of 4 or more. The particulate polymer B is a random copolymer including a (meth)acrylic acid ester monomer unit in a proportion of not less than 20.0 mass % and not more than 80.0 mass %.
