Abstract
Herein is disclosed an oxygen scavenging composition, comprising (i) an oxygen scavenging polymer comprising structure I:X—R—X—O—CH—Ar—CH—O,  (I) wherein —R— is selected from the group consisting of C–Calkyl, C–Csubstituted alkyl, C–Caryl, and C–Csubstituted aryl; —Ar— is selected from the group consisting of C–Caryl and C–Csubstituted aryl; and —X— is selected from the group consisting of null and —C(═O)—; (ii) a transition metal oxidation catalyst; and (iii) an energy-absorbing compound selected from the group consisting of microwave reactive materials and photoinitiators having a wavelength of maximum absorption of electromagnetic radiation from about 200 nm to about 750 nm. The oxygen scavenging composition can be used to form an oxygen barrier packaging article.
