    摘要: An oxygen scavenging polyolefin composition and methods of making thereof are described herein. In one approach, the composition includes a continuous non-polar polyolefin matrix having oxygen scavenging domains dispersed therein. The oxygen scavenging domains include an oxidizable polymer, a transition metal catalyst or salt thereof, and a catalytic promoter effective to bind with oxygen passing through the continuous non-polar polyolefin matrix. The oxygen scavenging domains forming a discrete polar region within the continuous non-polar polyolefin matrix. The composition further includes a polymeric compatibilizer having a polar moiety and a non-polar moiety and in amounts effective to uniformly disperse the polar oxygen scavenging domains in the continuous non-polar polyolefin matrix.
