The present invention provides a composition comprising: a polyester base polymer; an oxidizable polyether-based additive; and a transition metal catalyst, wherein the polyester base polymer is substantially free of antimony. Containers made include a wall made of the composition. The polyester base polymer may preferably include polyethylene terephthalate and include less than about 100 ppm of antimony, less than about 50 ppm, less than about 10 ppm, or between about 0 and about 2 ppm. Containers made from the composition are substantially clear and exhibit excellent oxygen scavenging properties with little to no induction period.
