Estimating the term…
A polymer blend composition, capable of being made electrically conductive by application of heat having an electrically conductive upon doping polymer in undoped form; the undoped polymer is selected from the group consisting of substituted and unsubstituted polyparaphenylenevinylenes, polyanilines, polyazines, polythiophenes, poly-p-phenylene sulfides, polyfuranes, polyselenophenes, polyacetylenes filtered from soluble precursors and combinations and blends thereof, compounded and blended at a molecular scale with a dielectric polymer; wherein the dielectric polymer is selected from the group consisting of interpolymers of acrylonitrile-butadiene-styrene, acetal acrylic liquid crystal polymers, polybutylene terephthalate, polycarbonate, polyester, polyetherimide, polyethersulfone, polyethylene, polyethylene terephthalate, polyphenylene oxide, polyphenylene sulfide, polypropylene, polystyrene, polyurethane, polyvinychloride, styrene-acrylonitrile copolymer, fluoropolymers, nylon polyesters, and thermoplastic elastomers, and a thermally deblockable dopant selected from the group consisting of triflates, tosylates and borates, the electrically conductive upon doping polymer having enhanced solubility in undoped form with said dielectric polymer to form a compatible molecularly mixed blend in solution; doping of the polymer occurs only after exposure to heat.
