    Abstract: Oxygen-scavenging polymers and packaging for holding oxygen-sensitive products. A heat treatment process has been found to significantly increase the oxygen-scavenging performance of the polymer. The enhanced scavenging polymer can be effectively incorporated into various packaging, including transparent multilayer containers for beer and juice. In one embodiment, a multilayer package made from the scavenger provides an actual reduction in oxygen content of a contents of the package, over a long period of time (e.g., 24 weeks). The package can be stored unfilled for an extended period (without significant loss of scavenging capability) and will scavenge substantially immediately upon filling with a liquid product. The package may incorporate a relatively low weight percentage of the scavenger, thus providing enhanced scavenging in a cost-effective manner.

    Abstract: An oxygen scavenging composition that can be either thermoplastic or thermoset, and that comprises at least one oxygen scavenging polymer and at least one curing agent is disclosed. The oxygen scavenging polymer comprises a polymeric backbone, at least two curing functional groups that are terminal groups and at least one oxygen scavenging cyclic moiety having from 5 to 9 carbon atoms in its ring and at least one carbon-carbon double bond in its ring. The curing functional groups of the oxygen scavenging polymer can be independently selected from hydroxyl groups, amino groups, carboxylic groups, sulfonic groups, and epoxy groups. The curing agent comprises at least two functional groups that are capable of reacting with the curing functional groups of the oxygen scavenging polymer.
