| 摘 要： | 用人工老化的方法比较了羧酸酯稀土和有机锡对聚氯乙烯（ＰＶＣ）的光老化稳定作用。借助于红外光谱和紫外／可见光谱，通过跟踪光老化过程中羰基基团和共轭双键的变化，发现羧酸酯稀土的抗脱ＨＣｌ能力优于有机锡，但抗氧化能力不如有机锡。

| Abstract: | Light ageing properties of poly(vinyl chloride)(PVC) by the carboxylic ester rare earth salt and the organotin have been compared by artificial ageing test.It bas been discovered that the carboxylic ester rare earth salt is superior to the organotin in antidehydrochlorination, and inferior to the organotin in antioxidation through following the tracks of carboxide group and conjugated double bond with the help of infrared spectroscopy and ultraviolet-visible spectroscopy. |
