ABSTRACT:
A composition for scavenging oxygen is disclosed. The composition comprises an ethylenically unsaturated hydrocarbon polymer which has 0.01-1.0 equivalents of carbon-carbon double bonds per 100 g of polymer and a transition metal catalyst and can be incorporated into various types of layers. The composition has an elongation-at-break of at least 20% and retains at least 50% of its original tensile strength after oxygen scavenging has occurred.
