Abstract
The present invention describes polymer compositions that have enhanced properties as oxygen barriers, as well as manufacturing methods for such oxygen-scavenging polymers and devices composed of such oxygen-scavenging polymers. These oxygen-scavenging polymers offer several benefits over existing materials, including a reduced ability for oxygen and carbon dioxide to permeate the polymer, reduced foaming of beverages stored in containers composed of the polymers, improved moisture absorption, and increased anti-bacterial/anti-fungal properties.
