Abstract:
A composition comprising a thermoplastic polymer and an oxygen scavenging composition, wherein the thermoplastic polymer comprises: polyesters, polyolefins, polyamides, polyurethanes, styrene: containing polymers and copolymers, polyacrylates, epoxy-amines, polyvinyl chloride, acrylonitrile containing polymers and copolymers, vinylidene chloride containing polymers and copolymers, polycarbonates, and ethylene copolymers and mixtures thereof, and the oxygen scavenging composition comprises: a) an oxidation catalyst, wherein the catalyst comprises at least one transition metal which can readily interconvert between at least two oxidation states; and b) at least one polyether selected from the group consisting of unsubstituted poly(alkylene glycol)s having alkylene chains of 1 to 3 carbon atoms, substituted or unsubstituted poly(alkylene glycol)s having alkylene chains of at least 4 carbon atoms, copolymers of poly(alkylene glycol)s, blends containing poly(alkylene glycol)s and mixtures thereof.
