    Abstract: The invention relates to synergistic combinations of certain phenolic antioxidants in thermoplastic polymers, especially in polyolefin pipes and other thermoplastic molding materials which are in prolonged contact with water. The instant combinations lead to better resistance against oxidative degradation as measured in terms of oxidation induction times (OIT), color and other technically important parameters as known in the art.
