Abstract: The disclosure of this application is directed to a composition which serves to improve the water-treeing resistance of polymeric compositions comprising a hydrocarbon-substituted diphenyl amine and a high molecular weight polyethylene glycol. Polymeric compositions containing the water-tree retardant additives are useful as extrudates about electrical conductors.
