Spectral Studies on the Effect of Rare Earth PoIy(Vinyl Chloride) Thermal Stabilizers

摘要

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