OXYGEN SCAVENGING COMPOSITIONS FOR PLASTIC CONTAINERS

摘要

The present invention provides an oxygen scavenging composition for incorporation into a wall of a package. The composition comprises a polyester base polymer, at least one oligomeric, oxidizable poly(alkylene ether) glycol-a,a, ?-diester having the formula (1) and at least one transition metal in a positive oxidation state. The compositions of the present invention do not exhibit an induction period prior to the onset of oxygen scavenging upon formation into a container.
