A vinylidene fluoride resin composition which comprises 100 parts by weight of vinylidene fluoride resin and 0.1 to 10 parts by weight of glycidyl (meth)acrylate resin, said glycidyl (meth)acrylate resin being a polymer composed of at least one of glycidyl acrylate and glycidyl methacrylate, or a copolymer composed of a monomer selected from the group consisting of methyl acrylate, methyl methacrylate, ethyl acrylate and ethyl methacrylate and at least one of glycidyl acrylate and glycidyl methacrylate. The resin composition has improved thermal stability and electrical properties, and is immune to deleterious discoloration.

Vinylidene fluoride resin composition containing glycidyl (meth)acrylate

A film prepared by molding a resin compound of a polyvinylidene fluoride admixed with a polycarbonate and/or a thermoplastic polyester and stretching into at least one direction is disclosed. The film shows excellent dielectric properties.

Dielectric film

Capacitor having layers of dielectric material containing at least one oriented film prepared by molding a resin composition comprising polyvinylidene fluoride, polycarbonate and/or thermoplastic polyester into un-stretched film and stretching the thus molded un-stretched film as at least a part of the constituents of the layer of dielectric material is disclosed.

Capacitor

Polyvinylidene fluoride film having its crystalline region occupied predominantly by form I crystals, characterized in that the crystals are substantially double oriented.
