Esters of polyalkyleneglycols with 3,5-dialkyl-4-hydroxyphenylalkanoic acids were prepared by simple esterification techniques. An example of such compounds is methoxytriethyleneglycol 3-(3',5'-di-t-butyl-4'-hydroxyphenyl)propionate. These compounds are useful as stabilizers of organic substrates subject to oxidative and thermal degradation.
聚烷基乙二醇与3,5-二烷基-4-羟基苯基丙酸酯的酯化反应通过简单的酯化技术制备而成。其中一种化合物的例子是甲氧基三乙二醇3-(3',5'-二叔丁基-4'-羟基苯基)丙酸酯。这些化合物可用作有机基质的稳定剂,防止氧化和热降解。
