摘要
用热烘法研究了羧酸酯稀土(CERES)对聚氯乙烯(PVC)的热氧稳定作用。借助于富里叶变换红外光谱(FTIR)分析.通过跟踪羰基基团在热老化过程中的变化,比较CERES与有机锡及两者的复合稳定剂对PVC的热氧稳定性能.
Thermal-oxidative stability of poly (vinyl chloride) (PVC) by carboxylic ester rare earth salt (CERES) has been studied during thermoexidativeageing in static condition in air. CERES, the organotin and their mixture have been compared as a thermal-oxidatime stabilizer with the help of Fourier transform infrared spectroscopy (FTIR).
