摘    要:稀土PVC热稳定剂量是最近才发展起来的一类高效、无毒的稳定体系。本文通过对稀土化合物作用下PVC降解的光声光谱和PVC傅里叶红外光谱的分析证明,稀土热稳定剂具有优越的稳定性能。稀土作用下PVC降解的光声光谱研究显示了稀土热稳定剂比其他热稳定剂具有更好的初色性能;红外光谱研究表明,稀土化合物的稳定作用是由于改变了PVC分子的构象,从而增加了PVC的稳定性。

关 键 词:聚氯乙烯  稀土  热稳定剂  光声光谱  红外光谱

Abstract:Rare earth Poly (Vinyl Chloride)(PVC) thermal stabilizers are one kind of effective and non toxic stabilizers developed recently.By photoacoustic (PA) spectra and FT IR analysis,their excellent performance in PVC stabilization progress can be studied conveniently.Good color remaining ability of rare earth stabilizers can be shown clearly by PA spectra and compared with others easily.From the IR spectrum and process data,the extra stabilization ability of rare earth stabilizers may be attributed to their conformation transforming effect.
Keywords:Rare earth    PVC stabilizer    Photoacoustic    FT  IR    Comformation
