| 摘 要： | 用热烘法研究了羧酸酯稀土对聚氯乙烯的热老化稳定作用。利用紫外／可见光谱分析跟踪共轭双键在热老化过程中的变化，比较ＣＥＲＥＳ，有机锡及两者的复合稳定剂的热老化稳定性能，发现ＣＥＲＥＳ与有机锡的稳定性能相当，复合稳定剂具有协同效应。

| Abstract: | Thermal stabibizations of poly (vinyl chloride) (PVC) by the carboxylic ester rare earth salt (CERS),the organotin and their mixture have been compared during thermoageing in static condictions in air by study of the ultraviolet-visible spectra. It has been proved that the CERES is equivalent to the organotin in thermal stabilization of PVC during thermoageing, and their mixture has synergistic combination. |
