    Abstract: The object of the invention is to provide a polyester composition that actively scavenges oxygen, with or without a transition metal catalyst. This was achieved by using a monomer selected from the group consisting of linear difunctional monomers having the general formula: X—(CH2)n—CH═CH—(CH2)m—X′ wherein X and X′ are each independently selected from the group consisting of OR and COOR, wherein R is selected from the group consisting of H and alkyl groups with one or more carbon atoms; and n and m are each independently 1 or more. The preferred monomer is 2-butene-1,4-diol (BEDO), and the preferred polyester is the reaction product of this diol with terephthalic acid to form poly(oxy-2-butene-1,4-diyloxycarbonyl-1,4-phenylenecarbonyl)—PBET. Copolymers of PBET are also within the scope of this invention. The polyester oxygen scavenging composition is then blended with conventional container resin such as polyesters, polyamides or polyolefins to make a container.

    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.
