Abstract : In the patent olefinic polymers (e.g., polyethylene) normally subject to accelerated oxidative degradation when used in contact with copper are stabilized for prolonged periods by inclusion of a hydrocarbyl ester of gallic acid (e.g., propyl gallate) together with a phenolic antioxidant for olefinic polymers. The compositions are especially useful for extending the service life of polyolefin copper wire insulation.
