稀土对聚氯乙烯塑料降解的共轭作用的光声光谱研究

Study on the Conjugated Effects of Degraded PVC with Rare Earth Stabilizers by Photoacoustic Spectroscopy

通过对稀土作用下PVC降解的光声光谱研究,分析了在稀土作用下PVC降解的共轭分布情况,结果表明,稀土PVC热稳定剂具有良好稳定性和初色性能。

Photoacoustic (PA) spectra of degraded PVC with rare earth stabilizers were studied and polyene distribution of degraded PVC was analyzed.Good color remaining ability and the extra stabilization ability of rare earth stabilizers can be shown clearly by PA spectra.
