Claim:
A melt blended polymer composition comprising: a. a base polymer; b. at least one compound having a structure of Formula I-VI present in an amount of from about 0.10 to about 10 weight percent of the composition; and c. a transition metal in a positive oxidation state, the metal present in an amount of from about 10 ppm to about 400 ppm; wherein Formula I and Formula II are compounds having the following structures: wherein the symbol --- when used in conjunction with a bond line represents a single or a double bond; wherein n is 3, 4, 5, or 6; wherein m 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, CR 1 , and CR 2 ; wherein D, E, and F are independently selected from the group consisting of CH, N, O, and S; and wherein each R 1 and each R 2 is independently selected from the group consisting of H, alkyl, aryl, electron withdrawing groups, electron releasing groups, and a transition metal; Formula III and Formula IV are compounds having the following structures: wherein 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, CR 1 and CR 2 ; wherein D, E, and F are independently selected from the group consisting of CH, N, O, and S; wherein each R 1 and each R 2 is independently selected from the group consisting of 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; and Formula V and VI are compounds having the following structures: wherein the symbol --- when used in conjunction with a bond line represents a single or a double bond; wherein each n is independently 0-5; wherein m 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, CR 1 , and CR 2 ; wherein D, E, and F are independently selected from the groups consisting of CH, N, O, and S; wherein each R 1 and each R 2 is independently selected from the group consisting of 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.
