摘　　要：2-（2-羟基-5-甲基苯基）-2H-苯并三唑（UV—P）系经重氮化，偶合，还原等反应制成。本文对用锌粉、水合肼、氢气等还原剂还原2-硝基-2’-羟基-5’-甲基偶氮苯制备UV—P的工艺进行了综述，还介绍了UV—P用于聚合物材料时的协同效应。2- （2- hydroxy - 5＇ - methylphenyl） - 2H - benzotriazol（ UV - P） were prepared by Diazotization, coupling and reduction. Reduction cyclization of 2 - nitro- 2＇ - hydroxy- 5＇ - methylazobenzene with such reducing agents as powdered zine, hydrazine hydrate, Hydrogen And others were reviewed and compared in detail. The application UV - P in Polymer materials were introduced. The synergism of UV - P and HALS is important in the Practical Photo- stabilization of plast.
