受阻胺光稳定剂的多功能性及其结构优化

Multifunction and Structure Optimization of Hindered Amine Light Stabilizer

简述了在高分子材料中受阻胺光稳定剂(HALS)作用的机理以及其他功能,并介绍了目前从结构上对受阻胺光稳定剂进行的性能优化的4种主要途径:高相对分子质量化,引入其他功能基团,低碱性化和提高相容性。

In this paper, hindered amine light tions were reviewed. Four main routes of structural stabilizer （HALS） activity mechanism and its other funcoptimization for conventional hindered amine light stabilizer molecules to achieve muhifunction or improved performance, i.e., to be high molecular weight, introduced other function groups, decreased alkaline and improved compatibility, were also introduced.
