摘　　要：介绍了耐药型受阻胺光稳定剂 (HALS)的发展。针对低 pKa值HALS ,含缚酸剂的HALS ,以及N 烷基化和N 烷氧基化HALS ,详细叙述了典型品种的性能特点 ,并报道了耐药型受阻胺光稳定剂的最新研究成果。The development of hindered amine light stabilizers (HALS) with chemical resistance is reviewed. Aiming at the low pKa HALS, Neutralizer/HALS blends, and the alkylamine or alkoxyamine HALS, their typical products and characteristics are introduced. The recent development on the HALS with chemical resistance is also reported.
