Summary: | Provided is a binder composition for a non-aqueous secondary battery electrode that can form an electrode having excellent peel strength and a secondary battery having excellent cycle characteristics. The binder composition for a non-aqueous secondary battery electrode contains a hindered phenol antioxidant and a particulate polymer formed of a graft polymer that includes a hydrophilic graft chain and that is obtained through a graft polymerization reaction of 1 part by mass to 40 parts by mass, in total, of either or both of a hydrophilic monomer and a macromonomer with 100 parts by mass of core particles containing a block copolymer that includes an aromatic vinyl block region formed of an aromatic vinyl monomer unit and an isoprene block region formed of an isoprene unit, and in which proportional content of the isoprene block region is 70 mass% to 99 mass%. |
