  • Patent number: 7923587
    Abstract: The present invention relates to macromonomer compounds possessing antioxidant properties, antioxidant polymers comprising the antioxidant macromonomers as a recurring unit, and methods of inhibiting oxidation in a substance comprising contacting the substance with the antioxidant polymers. In one embodiment, substantially all of the recurring macromonomeric units of the antioxidant polymers comprise an antioxidant moiety. In another embodiment, all of the recurring macromonomer units of the antioxidant polymers comprise an antioxidant moiety. The method of the present invention, yields antioxidant polymers with substantially all of the recurring units comprising an antioxidant moiety. These antioxidant polymers have greater bulk antioxidative properties than previously known.
