Abstract
A vinylidene fluoride copolymer containing a carboxyl group or a carbonate group is formed by copolymerizing a monomer principally comprising vinylidene fluoride with a relatively small amount of an unsaturated dibasic acid monoester or vinylene carbonate. The copolymer has a large adhesion to various substrates or fillers and is excellent in chemical resistance, so that it is useful as a basic substance constituting a binder, an adhesive, a paint, etc. The copolymer is particularly effectively used as a binder for constituting an electrode for a non-aqueous solvent-type secondary battery together with an active substance, or an active substance and an electroconductive material, respectively in a particulate form.
