摘要
本文研究了稀土有机化合物对聚氯乙烯稳定性能的影响,并从静态与动态条件下的热稳定性能、热分解特性曲线、老化性能等方面对稳定效果进行了评价。利用红外光谱分析及热分析(TGA-DTA)从微观结构角度探讨了稳定机理。
In this paper, the effect of rare-earth organic compounds on the stability of polyvinyl chloride is studied. And the stability is evaluated from the respects of thermal stability in static and dyn(?)mic conditions, respectively, thermal degradation characteristic curve and aging behaviour, etc. By using infrared spectrum analysis and thermal analysis (TGA-DTA), the methanism of the stabilization is approached in terms of mierostructure.
