Patent ID: 7691290

Claim:
A composition comprising: (a) at least one base polymer comprising a polyester polymer; (b) at least one non-polymeric oxidizable organic component present in an amount of about 0.10 to 10 weight present of the composition and the component comprising at least one compound of the formula E-(L-E) x wherein: E is L is a linking group of the formula —(O—R 21 ) z —O—, —(NH—R 21 ) z —NH—, —(NH—C(═O)R 22 ) t —NH, —NH—R 25 —NH(C(═O)R 26 NHR 25 NH) u —, —(O—R 23 —O—R 24 —C(═O) s —O— where L is attached to a carbon atom of Ar in structure (I) L; x is 0, 1, or 2; Ar is aryl or heteroaryl; R 1 and R 2 are each independently, H, C 1 -C 12 alkyl, C 1 -C 6 alkoxy, C 6 -C 20 aryloxy, hydroxy, C 2 -C 6 alkenyl, NR 19 R 20 , acetyl, nitro, glyceryl, carbohydrate, —C(═O)H, L, or two R 1 or two R 2 groups form a group of the formula —O—R 18 —O; R 3 and R 4 are each H; R 5 to R 10 are each, independently, H or C 1 -C 3 alkyl; R 18 is C 2 -C 6 alkyl; R 19 and R 20 are each, independently, H, C 1 -C 6 alkyl, or C 6 -C 20 aryl; R 21 and R 24 are each, independently, C 1 -C 6 alkyl; R 22 , R 23 , R 25 and R 26 are each, independently, C 1 -C 6 alkyl or C 6 -C 20 aryl; n and p are independently 0 or an integer from 1 to 5; s and z are, independently 1, 2, or 3; t and u are, independently 1 or 2; and (c) at least one transition metal in a positive oxidation state, the metal being present in the composition in an amount of 10 to 400 ppm.
