Effect of the 2:1 combination of Na and Zn stearates on the stabilization of PVC exposed to thermal stress at 180 Β° in air has been studied by i.r. spectrometry (190(~1350cm 1) and by determination of Zn, Na and CI-in the decomposition products of the stearates (NaCI, ZnCI2). Complexation of both co
A~tract--Infra-red spectra (2300-2000 cm ~) were studied for cast PVC films obtained after separation of the unreacted, partly deuterated Cd stearate from samples subjected to thermal degradation at 180" in air. Based on the absorbance at 2140 cm -1 corresponding to the C-D stretching vibration, the
