title: [Spectral studies on the mechanism of rare earth poly (vinyl chloride) thermal stabilizers].
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.
