First claim
Opening claim text (preview).
What is claimed is: 1. An oxygen scavenging master batch composition consisting of: (a) a transition metal compound; and (b) an oxygen scavenger compound having a structure selected from: wherein the transition metal compound 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 transition metal compound comprises cobalt. 3. The composition of claim 2 , wherein the transition metal compound is a cobalt carboxylate or cobalt neodecanoate. 4. The composition of claim 1 , wherein the oxygen scavenger compound is present in a weight percent amount of about 50% to about 90%. 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) a transition metal compound; and (b) an oxygen scavenger compound having a structure selected from: under conditions effective to provide an oxygen scavenging master batch composition; wherein the transition metal compound is present in an amount greater than about 500 ppm (by metal) weight percent based on the weight of the oxygen scavenging master batch composition, and wherein the oxygen scavenging master batch composition consists of the transition metal compound and the oxygen scavenger compound. 7. The method of claim 6 , wherein the transition metal compound comprises cobalt. 8. The method of claim 7 , wherein the transition metal compound is a cobalt carboxylate or cobalt neodecanoate. 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.
