Abstract
A method for producing a binder composition for a storage battery device, which comprises an emulsion polymerization step of emulsion polymerizing a monomer mixture containing a fluorinated vinyl monomer in the presence of a first anionic emulsifying agent (A), an aqueous medium and a radical polymerization initiator to obtain a latex containing a fluorinated polymer, and a post addition step of adding a second anionic emulsifying agent (B) to the latex. The first anionic emulsifying agent (A) has no phenyl group in its molecule, and the second anionic emulsifying agent (B) has a phenyl group in its molecule.
