OXYGEN SCAVENGING COMPOSITIONS COMPRISING POLYMERS DERIVED FROM AROMATIC DIFUNCTIONAL MONOMERS

Document Type and Number:

WIPO Patent Application WO2003053171

Kind Code:

A3

Abstract:

Herein is disclosed an oxygen scavenging composition, comprising (i) an oxygen scavenging polymer comprising units having structure (I):, wherein R<1> and R<2> are independently selected from the group consisting of -O-, -NCO-, and -NR-, wherein R is selected from the group consisting of -H and C1-C6 alkyls; (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 scavenging packaging article.
