国内受阻胺类光稳定剂合成研究新进展

Research progress in HALS synthesis in China

受阻胺类光稳定剂(HALS)具有优异的抗老化性能,其合成研究一直是抗老化领域科研工作者的研究重点。本文从商品化产品的工艺优化、新型HALS的合成研究、含烷氧基团的受阻胺结构(NOR型)HALS的烷氧基化方法三个方面论述了近十年国内HALS合成的研究情况。

Hindered amine light stabilizer(HALS)is a kind of excellent anti-aging additives of polymer materials and its synthesis routes have always been the focus for researchers.In this paper,we discussed the hindered amine light stabilizer(HALS)synthesis in China over the last decade in three aspects of optimized process of commercial HALS products,synthesis research of new HALSs,and the methods of alkylation reaction of NOR-type HALSs.
