A study of the thermal degradation of poly(vinyl chloride) in the presence of carbazole and potassium carbazole using t.g.a./FTi.r.

Thermal properties of blends containing poly(vinyl chloride) and carbazole or potassium carbazole in different molar ratios were investigated using thermogravimetric analysis coupled with Fourier transform infra-red spectroscopy. The effect of additives on the polymer degradation process, and especially on the evolution of hydrogen chloride, was studied. Finally, mechanisms of stabilization were proposed.
