VINYLIDENE FLUORIDE COPOLYMER AND USE OF THE COPOLYMER

摘要

PROBLEM TO BE SOLVED: To provide a vinylidene fluoride copolymer excellent in adhesiveness with a base material such as metal, and to provide a binder for a battery electrode and a combined agent for a non-water electrolyte secondary battery containing the above copolymer, an electrode for a non-water electrolyte secondary battery obtained by using the above combined agent, and a non-water electrolyte secondary battery having the electrode.

SOLUTION: The copolymer includes structural units expressed by general formulae a, b and c. In general formulae b and c, RN,Srepresents an organic group containing nitrogen and/or sulfur.
