硫代双酚抗氧化剂/聚乙二醇共混物
摘要：
通过首先形成抗氧化剂与聚亚烷基二醇（PAG）的共混物（优选干共混物）并然后将该共混物与聚乙烯共混有效地将硫代双酚抗氧化剂与抗树的可交联聚乙烯干共混或熔融混合。将硫代双酚抗氧化剂与PAG的共混物加入聚乙烯中为PE提供了高的氧化诱导时间（OIT），其是PE的氧化稳定性的量度。
摘要（英）：

Thiobis phenolic antioxidants are efficiently dry or melt blended with a tree-resistant, crosslinkable polyethylene by first forming a blend, preferably a dry blend, of the antioxidant with a polyalkylene glycol (PAG), and then mixing the blend with the polyethylene. The incorporation of thiobis phenolic antioxidant and PAG blend into polyethylene provides the PE with high oxidative induction time (0IT) which is a measure of the oxidative stability of the PE.
