Post-coupling synthetic approach for polymeric antioxidants

A composition comprising:

• an antioxidant polymer and one or more components selected from the group consisting of:
• an edible product, a packaging material, a soap, a cosmetic agent, a petroleum product, a lubricant, a paint, an elastomer, a pharmaceutically active agent, a synthetic monomeric or oligomeric antioxidant, a natural monomeric or oligomeric antioxidant, and a preservative, wherein the antioxidant polymer includes at least one repeat unit represented by a structure selected from the group consisting of Structural Formulas (I), (II), (III), (IV) and combinations thereof:
• wherein:
• R′ is a covalent bond, —O—, —C(O)O—, —C(O)N—, —C(O)—, —CH═CH—, —S— or —N—;
• R1 is —H or an alkyl group, or —(CH2)k—O—X—Z;
• each X is independently a covalent bond, —C(O)—, —C(O)O— or —C(O)N—;
• Y is —O—, —N— or —S—;
• each Z is an independently selected antioxidant;
• a is an integer from 0 to 12;
• each k is independently an integer from 0 to 12;
• m is an integer from 0 to 6;
• n is 0 or 1;
• and
• p is an integer from 0 to 6, and wherein when the repeat unit is represented by Structural Formula (I), (II) or (III), Z is selected from the group consisting of
• a 3,4,5-trihydroxyphenyl group, 4-acetoxy-3-tert-butylphenyl group, a 3-alkoxycarbonyl-2,6-dihydroxyphenyl group, a 3-propoxycarbonyl-2,6-dihydroxyphenyl group, a 3,5-di-tert-butyl-2-hydroxyphenyl group, a 3-tert-butyl-4-hydroxyphenyl group, a 2,6-di-tert-butyl-4-mercaptophenyl group, a 2,6-di-tert-butyl-4-hydroxyphenyl group, a 3,4-methylenedioxyphenyl group, a 3,5-di-tert-butyl-4-hydroxybenzenethiol, 2-(3,5-di-tert-butyl-4-hydroxyphenyl) acetic acid, 3,5-di-tert-butyl-4-hydroxybenzoic acid, 3,5-di-tert-butyl-4-hydroxycinnamic acid, gallic acid, alkyl gallates, 3,5-di-tert-butyl-4-hydroxybenzyl alcohol, tert-butyl-hydroquinone, 2,5-di-tert-butyl-hydroquinone, 2,6-di-tert-butyl-hydroquinone, 3,5-di-tert-butyl-4-hydroxybenzaldehyde, monoacetoxy-tert-butylhydroquinone, sesamol, isoflavones, flavanoids and coumarins.
