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.

R1-R3 may be joined together to form a cyclic structure. Or R3: OR in which R: a group selected independently from one another from the groups consisting of H, an optionally substituted C1-C20 alkyl group, an optionally substituted C6-C20 aryl group, an optionally substituted C7-C20 alkylaryl group, and an optionally substituted C7-C20 arylalkyl group and at least one of R1, R2 and R3 are joined together and form a cyclic structure containing less than 5 carbon atoms. The co-catalyst is at least one of an alkaline metal salt, earth alkaline metal salt or an ammonium salt. The invention further relates to a process to increase the rate of oxygen-uptake by a polymer composition. The invention also relates to a process to increase the oxo-biodegradability of a polymer composition and to the use of such a composition for the preparation of a product having a controlled lifetime. The invention further relates to a process to increase the rate of oxygen-scavenging in a composition containing a carbon-containing polymer, the composition obtained by this method and its use in the preparation of an oxygen-scavenging product. The present invention further relates to objects containing an oxygen scavenging layer containing such a composition.

Abstract: An oxygen scavenger composition includes mer units that have at least one cycloalkenyl group or functionality and, further, has mer units derived from isophthalic acid or terephthalic acid or certain derivatives thereof. The oxygen scavenger composition has been found to act as an oxygen scavenger under both ambient and refrigeration conditions, to be compatible with conventional film forming packaging materials, to inhibit undesirable oligomer formation and oxidation by-product formation, and to be readily formable and processable using conventional film forming equipment. A film and laminated product having said oxygen scavenger composition are also disclosed.
