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 ethylene-vinyl acetate copolymers blended with ethylene/vinyl acetate/CO terpolymers. 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.

La présente invention concerne des mélanges de copolymères ayant un certain pourcentage de monomère d'acétate de vinyle avec un terpolymère ayant un certain pourcentage d'acétate de vinyle. Cette composition confère des propriétés de résistance à la chaleur et à la flamme à des fils, des câbles, ou autres produits manufacturés fabriqués à partir de telles compositions. Les mélanges préférés comprennent ou comportent essentiellement des copolymères éthylène-acétate de vinyle mélangés à des terpolymères éthylène/acétate de vinyle/CO. Ces mélanges sont préparés en combinant les ingrédients à d'autres excipients choisis parmi le trihydrate d'aluminium, le noir de carbone, l'acide stéarique, le tri(2-méthoxyéthoxy) vinyle silane, un phénol protégé polymère, dilaurylthiopropionate, N,N'-m-phénylènedimalémide, et .alpha.,.alpha.'-bis(t-butylperoxy)diisopropylbenzène. Les mélanges de l'invention constituent en fait des succédanés de copolymères éthylène-acétate de vinyle à haute teneur en acétate de vinyle.
