Abstract: Conductive curable compositions contain a free radical polymerizable monomer, oligomer or polymer (i); an organoborane amine complex (ii), and an electrically or thermally conductive filler (iii). The conductive curable compositions can also contain an amine reactive compound having amine reactive groups (iv); and (v) a component capable of generating a gas when mixed with a compound bearing active hydrogen and a catalyst. The electrically conductive curable compositions can be used in composite articles of manufacture in which substrates are coated or bonded together with the composition and cured; and as electrically conductive rubbers, electrically conductive tapes, electrically conductive adhesives, electrically conductive foams, and electrically conductive pressure sensitive adhesives.
