摘要
紫外线吸收剂是一类可防止太阳光或其他人造紫外光引起聚合物降解的物质。2-（2′-羟基苯并三唑、2-羟基二苯酮、水杨酸酯等可用作紫外线吸收剂，本文综述了其合成和应用的情况，该类产品的改性使之性能更好，可用于一些工程塑料中。
Ultraviolet stabilizers are organic substance that protect polymeric and other light-sensitive Materials from degradation by sunlight and artifical soures of UV. Several different classes of compoundsare used , including 2-（2＇-hydroxyphenyl）benzotriazoles , 2-hydroxybenzophenones , aryls salicylate and other.The synthesis and application of ultraviolet stabilizers were revewed in this paper . The recent research progress in modified it were also introduced. The modified products have more fine performance ,wich make it possible to use in some engineering plastics.
