| 摘 要： | <正> 2,2,6,6四甲基哌啶类受阻胺化合物是一类新型的光稳定剂。由于它们都有较低的离子化电位,因此有着较强的猝灭单线态氧的能力。在猝灭单线态氧的过程中哌啶基可氧化生成稳定的氮氧自由基,这种稳定自由基可以再进一步在高分子光稳定中起到作用。它能清除高分子降解或氧化过程中产生的能引起高分子进一步降解的活性自由基,以及通过其它途径起到稳定作用。

| Abstract: | In this study, the process of photosensitization oxidation of poly (styrene-co-2, 2, 6, 6 tetramethyl-4-piperidinylmethacrylate) and 2, 2, 6, 6 tetramethyl-4-piperidinol were compared. It was shown that, the copolymer stated above can accumulated more quantity of stable free radical than another one under same condition.In the experiments of quenching effect for fluorescence of pyrene, the effect of copolymer is similar to the low molecular compound. |
