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.
本文描述了一种氧清除聚烯烃组合物及其制造方法。在一种方法中,组合物包括连续的非极性聚烯烃基体,其中分散有氧清除结构域。氧清除结构域包括可氧化聚合物、过渡金属催化剂或其盐,以及可与通过连续非极性聚烯烃基质的氧气有效结合的催化促进剂。氧清除域在连续非极性聚烯烃基质中形成一个离散的极性区域。该组合物还包括一种具有极性分子和非极性分子的聚合物相容剂,其用量能有效地将极性氧清除结构域均匀地分散在连续的非极性聚烯烃基体中。
