ABSTRACT:
A vinylidene fluoride copolymer having a relatively high molecular weight is formed by copolymerizing (a) vinylidene fluoride as a principal component, (b) a small amount of epoxy group-containing monomer, and (c) an optional component, such as an unsaturated dibasic acid monoester functioning as a curing agent for the epoxy group. When cured with an optional epoxy curing agent, the vinylidene fluoride copolymer provides a cured product having an adhesion with a metal substrate, etc., and also showing excellent solvent resistance and chemical resistance. The vinylidene fluoride copolymer is particularly suitable for constituting a binder for producing an electrode for a non-aqueous solvent-type secondary battery.
