Abstract
Rigid containers are provided comprising oxygen scavenger compositions that produce only low levels of volatiles or by-products as a consequence of oxygen scavenging. In particular, a family of polymers containing selected cyclic olefinic pendent groups are used in the rigid containers to achieve oxygen scavenging that is associated with minimal or no organoleptic by-products after oxidation.
