1. A method of making an oxygen scavenging polymer comprising the step of providing a monomer comprising a moiety having the structure: wherein the symbol --- when used in conjunction with a bond line represents is a single or a double bond; wherein n is 3, 4, 5, or 6; wherein in is an integer from 0 to 6-n; wherein each X is independently selected from the group consisting of O, S, and NH; wherein each Y, each A, and each B are independently selected from the group consisting of N, CR1, and CR2; wherein D, E, and F and independently selected from the group consisting of CH, N, O, and S; and wherein each R1 and each R2 is independently selected from the group consisting of carboxylic acid, amine, nitro cyano, hydroxyl, H, alkyl, aryl, electron withdrawing groups, electron releasing groups, and a transition metal: when in the symbol --- when used in conjunction with a bond line represents a single or a double bond; wherein each n is independently 1-5; wherein m is an integer from 0 to 5-n; wherein each X is independently selected from the group consisting of O, S, and NH; wherein each Y, each A, and each B are independently selected from the group consisting of N, CR1, and CR2; wherein D, E, and F are independently selected from the group consisting of CH, N, O, and S; wherein each R1 and each R2 is independently selected from the group consisting of carboxylic acid, amine, nitro, cyano, hydroxyl, H, alkyl, aryl, electron withdrawing groups, electron releasing group, and a transition metal; and wherein L is a divalent linking group selected from C2-C12 aliphatic or cyclic ether, C2-C12 aliphatic or cyclic amide, C6 to C12 aromatic amide, C2-C12 aliphatic or cyclic amine, C6-C12 aromatic amine, C2-C12 aliphatic or cyclic ester and C6 to C12 aromatic ester, wherein the symbol --- when used in conjunction with a bond line represents a single or a double hand; wherein each n is independently 0-5; wherein in is an integer from 0 to 5-n; wherein each X is independently selected from the group consisting of O, S, and NH; wherein each Y, each A, and each B are independently selected from the group consisting of N, Cr1 and CR2; wherein D, E, and F are independently selected from the group consisting of CH, N, O, and S; wherein each R1 and each R2 is independently selected from the group consisting of carboxylic acid, amine, nitro, cyano, hydroxyl, H, alkyl, aryl, electron withdrawing groups, electron releasing groups, and a transition metal; and wherein L is a divalent linking group selected from C2-C12 aliphatic or cyclic ether, C2-C12 aliphatic or cyclic amide, C6 to C12 aromatic amide, C2-C12 aliphatic or cyclic amine, C6-C12 aromatic amine, C2-C12 aliphatic or cyclic ester and C6 to C12 aromatic ester; or wherein each X is selected from the group consisting of O, S, and NH; wherein each Y, each A, and each B are independently selected from the group consisting of N and CR1; wherein D, E, and F are independently selected from the group consisting CH, N, O, and S; wherein the symbol --- when used in conjunction with a bond line represents a single or a double bond; and wherein each R1 is independently selected from the group consisting of H, alkyl, aryl, electron withdrawing groups, and electron releasing groups during polymerization of polyethylene terephthalate.
