Disclosed are: a binder composition for a non-aqueous secondary battery in which the adhesion between a battery active material and a current collector is excellent, the degree of swelling of an electrode with electrolytic solution at a high temperature is small, and can exhibit practical performance satisfactorily; an electrode mix for a non-aqueous secondary battery, which is produced using the binder composition; a process for producing an electrode for a non-aqueous secondary battery; and a non-aqueous secondary battery. Specifically disclosed are: a binder composition for a non-aqueous secondary battery, which comprises a binder and a solvent or a dispersion medium, wherein the binder comprises a fluorinated copolymer having a repeating unit derived from ethylene tetrafluoride and a repeating unit derived from propylene, and wherein the fluorinated copolymer has a weight average molecular weight of 10,000 to 300,000; an electrode mix for a non-aqueous secondary battery, which is produced using the binder composition; a process for producing an electrode for a non-aqueous secondary battery; and a non-aqueous secondary battery. |
