摘要
聚合物尤其是存在弱链键和双烯结构的大分子链,在接受太阳紫外线辐射后,易发生光诱发的氧化降解反应(老化)。为抑制或延缓聚合物的光氧老化速度,目前人们惯用的措施是添加紫外光稳定剂、抗氧剂和重金属离子钝化剂。本文较为系统地论述了紫外光稳定剂和抗氧剂等有机化合物的化学分子结构特征和它们的功能团所发挥的作用机理。
Photooxy-degradation （aging） will happen to polymer when they accept UV-irradiation of the sun especially weak bond or unsaturated bond as diolefine exist in macromolecular chain. We usually add UV-stabilizers, antioxidants and metal-ion deactivators to protect polymer or detain their ageing speed.
This article described integrally the relation between the characteristic active group of their chemical structure and mechanism of stabilization.
