Oxygen scavenging compositions comprising polymers derived from benzenedimethanol monomers

摘要

Herein is disclosed an oxygen scavenging composition, comprising (i) an oxygen scavenging polymer comprising structure I: X-R-X-O-CH2-Ar-CH2-O , (I) wherein -R- is selected from the group consisting of C1-C24 alkyl, C1-C24 substituted alkyl, C6-C24 aryl, and C6-C24 substituted aryl; -Ar- is selected from the group consisting of C6-C24 aryl and C6-C24 substituted 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.
