摘要
苯骈三唑、邻羟基二苯甲酮、水杨酸酯类化合物构成了几种重要类型的紫外吸收剂。本论文研究了反应型和共混型紫外吸收剂在聚苯乙烯体系中的抗光氧化降解行为,对其紫外吸收及光氧化降解的内在机理予以探讨。
Benzotriazole, o - hydroxyl benophenone, salicylic acid and esters comprise several important types of ultraviolet - absorbents(UAS). In this paper we have studied the action of photo - oxidation degradation in system of styrene which co - polwnerizes with reactive - type UAS and co-blended - type UAS, and probed internal mechanisms of ultraviolet - absorption and photo -oxidation degradation.
