Abstract
The present invention relates to blends of copolymers having a certain percentage of vinyl acetate monomer with a terpolymer having a certain percentage of vinyl acetate wherein the composition provides heat and flame resistant properties to wires and cable or other manufactured goods prepared from such compositions. The preferred blends comprise or consist essentially of alkylene-vinyl acetate copolymers blended with alkylene/vinyl acetate/CO terpolymers selected from, for example, ethylene-vinyl acetate and ethylene/vinyl acetate/carbon monoxide. The blends are prepared by combining the ingredients with other excipients selected from aluminum trihydrate, carbon black, stearic acid, tri(2-methoxyethoxy) vinyl silane, polymeric hindered phenol, dilaurylthiopropionate, N,N'-m-phenylenedimalemide, and .alpha.,.alpha.'-bis (t-butylperoxy)diisopropylbenzene. The blends of the invention actually simulate a high vinyl acetate content EVA.
