稀土无机盐对聚氯乙烯热稳定作用的研究

Effect of Rare Earth Inorganic Compound on Heat Stability of PVC

本文着重研究了不同品种、不同组分配比的稀土无机化合物及其与稀土有机盐复合对聚氯乙烯热稳定性的影响，并对其作用机理进行了初步探讨。

The effects of rare earth inorganic compounds of different kinds, compositions and combinations of rare earth inorganic and organic compounds on the heat stability of PVC were studied in this paper. The heat stabilizing mechanism of the stabilizers was also studied preliminarily.
