First claim
Opening claim text (preview).
What is claimed is: 1. An oxygen scavenging master batch composition consisting of: (a) one or more transition metal compounds; and (b) one or more oxygen scavenger compounds having a structure selected from wherein the one or more transition metal compounds is present in an amount greater than about 500 ppm (by metal) based on the total weight of the oxygen scavenging master batch composition. 2. The composition of claim 1 , wherein the one or more transition metal compounds comprises cobalt. 3. The composition of claim 2 , wherein the one or more transition metal compounds is a cobalt carboxylate, a cobalt neodecanoate, or a combination thereof. 4. The composition of claim 1 , wherein the one or more oxygen scavenger compounds is present in a weight percent amount of about 50% to about 90% based on the total weight of the oxygen scavenging master batch composition. 5. An article of manufacture comprising the composition of claim 1 . 6. A method of making an oxygen scavenging master batch composition comprising the step of combining: (a) one or more transition metal compounds; and (b) one or more oxygen scavenger compounds having a structure selected from under conditions effective to provide an oxygen scavenging master batch composition; wherein the one or more transition metal compounds is present in an amount greater than about 500 ppm (by metal) weight percent based on the total weight of the oxygen scavenging master batch composition, wherein the oxygen scavenging master batch composition consists of the one or more transition metal compounds and the one or more oxygen scavenger compounds. 7. The method of claim 6 , wherein the one or more transition metal compounds comprises cobalt. 8. The method of claim 6 , wherein the one or more transition metal compounds is a cobalt carboxylate, a cobalt neodecanoate, or a combination thereof. 9. The method of claim 6 , wherein the conditions effective to provide comprise blending or compacting the components, and extruding the composition. 10. The method of claim 6 , wherein the conditions effective to provide comprise melt blending the components. 11. The method of claim 9 , wherein the extruding is in the absence of a binder. 12. The method of claim 6 , wherein the one or more oxygen scavenger compounds is present in a weight percent amount of about 50% to about 90% based on the total weight of the oxygen scavenging master batch composition.
