- 1 - ORGANOFUNCTIONAL SILANE-SILOXANE OLIGOMER COUPLING COMPOSITIONS, CURABLE AND CURED ELASTOMERIC COMPOSITIONS CONTAINING SAME AND NOVEL ELECTRICAL CABLE CONTAINING SAID CURED ELASTOMERIC COMPOSITIONS Abstract Of The Disclosure Novel coupling compositions for improving adhesion between an organic elastomer and an inorganic substrate comprise (A) an ethylenically unsaturated silane, having bonded to silicon, at least one hydroxy group and/or alkoxy group reactive with the inorganic substrate and at least one ethylenically unsaturated group polymerizable with the organic elastomeric matrix; (B) an organosiloxane oligomer, having bonded to silicon, at least one hydroxy and/or alkoxy group reactive with said inorganic substrate; and (C) optionally, an ethylenically unsaturated organosiloxane oligomer, having bonded to silicon, at least one ethylenically unsaturated group polymerizable with said organic elastomeric matrix. The novel curable compositions contain the novel coupling compositions, an organic elastomer, an inorganic filler, and a peroxide crosslinking agent. The novel cured compositions are produced by heating the novel curable composition to a temperature above the decomposition temperature of the peroxide thereby inducing crosslinking of the organic elastomer. The novel electrical cable comprises a conductor having a coating of insulation which comprises the novel cured composition. S P E C I F I C A T I O N
