抗氧剂作用机理及应用

The Action Machanism And Application of Antioxidant

塑料线性高分子链具有易被氧化特性,论述了该氧化过程是以自由基反应循环为主要特征的反应机理以及诱发和影响因素,抗氧剂作用机理是通过清除该反应过程中的自由基来阻止反应链循环;根据阻止主、副反应循环将抗氧剂分为主、辅助抗氧剂两大类;论述了各自及协同作用机理。本文还介绍了一些常用的抗氧剂。

The chain of plastic linear high molecular had the property of being oxidized easily,The oxidation process was reviewed that reaction mechanism had the briefly specific property of freedical reaction cycle and the factors of inducement and effect,The antioxidant's reaction mechanism obstructed the reaction chain cycle through eliminating the freedical in reaction process;There were divided in two kinds of brief and auxiliary antioxidant on the basis of preventing the brief and auxiliary reaction cycle,The each and cooperative action mechanism were discussed.This paper introduced some usual antioxidant,yet.
