Oxygen scavenging polymer blends and emulsion-based methods for preparing same

摘要

Herein is disclosed a blend of a neat oxygen scavenging polymer and a second polymer. The blend can be prepared by extrusion of a neat formulation of the oxygen scavenging polymer and the second polymer. Also disclosed are methods for preparing the neat formulation of the oxygen scavenging polymer, and packaging articles prepared from the blend. In addition, compositions comprising a branched oxygen scavenging polymer and a second polymer are disclosed, as well as packaging articles prepared from such compositions.
