摘要
用紫外-可见光谱法与付里叶变换红外光谱法研究聚苯乙烯以及苯乙烯-丙烯酸酯共聚物的老化过程。在光、热、氧的作用下,这些聚合物的部分主链与侧苯基断裂,有少量苯乙酮结构生成,导致材料变色。
Aging of polystyrene and styrene-acrylate copolymers had been quantitatively investigatedwith UV-Vis and FITR spectroscopy.Under the action of light,heat and oxygen,somemain chains and side benzene groups of these polymers were broken off. A littleacetophenone structures appeared,and made the materials coloured.
