Abstract: The present invention provides a composition comprising: a polyester base polymer; at least one non-polymeric oxidizable organic compound; at least one transition metal in a positive oxidation state, said metal being present in the composition in an amount of from about 10 to about 400 ppm, wherein the polyester base polymer comprises less than about 40 ppm phosphorous. The compositions of the present invention do not exhibit an induction period prior to the onset of oxygen scavenging upon formation into a container.
