    • Disclosed is a process for esterifying and/or transesterifying a polymer having a polyethylenic backbone and pendant acid and/or ester moieties comprising contacting a melt of the polymer with a transesterifying compound so that the polymer undergoes esterification and/or transesterification but not alcoholysis. The esterified or transesterified polymer also has pendant ester moieties which differ in kind and/or number from the unreacted polymer. In one embodiment, the process also comprises adding an amount of a transition metal salt that is effective to promote oxygen scavenging. Also in a further embodiment, the process comprises irradiating the transesterified polymer with actinic radiation to reduce the induction period before oxygen scavenging commences. Also disclosed are compositions comprising a component which comprises an ethylenic or polyethylenic backbone and a pendant or terminal moiety comprising a benzylic, allylic, or ether-containing radical. The invention also embodies new polyethylenic oxygen scavenging compositions comprising a transition-metal salt and the above component. Methods of making the compositions, and methods and compositions using the ethylenic or polyethylenic compositions, are disclosed.
    • 公开了一种使具有聚乙烯主链和侧酸和/或酯部分的聚合物酯化和/或酯交换的方法,包括使聚合物的熔体与酯交换化合物接触,使得聚合物经历酯化和/或酯交换而不是醇解。 酯化或酯交换的聚合物还具有与未反应的聚合物不同的类型和/或数量的侧链酯部分。 在一个实施方案中,该方法还包括加入一定量的有效促进除氧的过渡金属盐。 同样在另一个实施方案中,该方法包括用光化辐射照射酯交换聚合物以减少氧清除开始前的诱导期。 还公开了包含包含烯属或聚乙烯主链的组分和包含苄基,烯丙基或醚的自由基的侧链或末端部分的组合物。 本发明还体现了包含过渡金属盐和上述成分的新型聚亚乙基氧清除组合物。 公开了制备组合物的方法,以及使用烯属或聚烯烃组合物的方法和组合物。
