Patent ID: 7413815

Claim:
A multilayered construction suitable for forming capacitors which comprises: a) a first electrically conductive layer, having first and second surfaces; b) a first thermosetting polymer layer, having first and second surfaces, on the first electrically conductive layer with the first surface of the first thermosetting polymer layer on the second surface of the first electrically conductive layer; c) a central polymerizable layer, having first and second surfaces, on the first thermosetting polymer layer with the first surface of the central polymerizable layer on the second surface of the first thermosetting polymer layer, which central polymerizable layer comprises a polymerizable precursor of a polyethylene terephthalate, a polyethylene naphthalate, a polyvinyl carbazole, a polyphenylene sulfide, an aromatic polyamide, a polyether-nitrile, a polyether-ether-ketone, or combinations thereof; d) a second thermosetting polymer layer, having first and second surfaces, on the central polymerizable layer with the first surface of the second thermosetting polymer layer on the second surface of the second surface of the central polymerizable layer; and e) a second electrically conductive layer, having first and second surfaces, on the second thermosetting polymer layer with the first surface of the second electrically conductive layer on the second surface of the second thermosetting polymer layer; wherein each of said first thermosetting polymer layer, said second thermosetting polymer layer and said central polymerizable layer optionally further comprises a filler material.
