    摘要: Methods of preparing an antioxidant polymer are described comprising polymerizing macromonomers that comprise an antioxidant. By having the antioxidant as part of the macromonomer, a polymer with a higher density of antioxidants is prepared more efficiently than coordinating antioxidants to an already formed polymer. The methods of polymerization also encompass copolymerization wherein different macromonomers comprising different antioxidants may be used. Alternatively, the other macromonomer, or monomer, may not include an antioxidant depending on the intended use of the copolymer and desired properties. The macromonomer comprising a antioxidant may comprise more than one antioxidant which may be the same or different. In one embodiment, the macromonomer is benzene or olefin based, wherein the benzene or olefin is substituted with an antioxidant.
