COMPOSITIONS, ARTICLES AND METHODS FOR SCAVENGING OXYGEN WHICH HAVE IMPROVED PHYSICAL PROPERTIES

Document Type and Number:

WIPO Patent Application WO/1994/007944

Kind Code:

A1

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.
