探索了一种研究 PVC热稳定剂作用模式的数学方法 ,所建立的曲线回归方程有效地反映了热稳定剂类型的差异 ;采用红外光谱研究表明稀土热稳定剂的作用可以改变 PVC分子的构象 ,增加 PVC的稳定性
A mathematical method for studying the mode of action of PVC heat stabilizer was explored. The curve regression equation established effectively reflected the difference of the type of heat stabilizer. The infrared spectroscopy showed that the effect of rare earth heat stabilizer could change the conformation of PVC molecule, Increase the stability of PVC
