实验表明受阻胺光稳定剂(HALS)能牢固地与过渡金属离子络合。在空气中进行这种反应时,各种金属离子呈现出显著的氧化作用的趋势,这种反应通常是表现在横排第一系列的过渡金属上,除了从其它研究工作得到证明之外,我们还可通过这些研究结果提出这样一个概念,这些受阻胺类稳定剂由于具有络合能力,它们将会对聚合物起光氧化稳定剂的作用。初步的试验结果还表明,受阻胺类也可以与非过渡金属络合。 Experiments show that hindered amine light stabilizer (HALS) can be firmly complexed with transition metal ions. When conducting this reaction in air, the various metal ions exhibit a pronounced tendency to oxidize, and this reaction is usually manifested in the first series of transition metals. In addition to the evidence from other studies, we It is also possible to draw from these findings the notion that these hindered amine stabilizers, due to their ability to complex, will act as photooxidation stabilizers for the polymers. The preliminary test results also show that hindered amines can also complex with non-transition metals.
