Abstract

The thermal degradation behavior of poly(vinyl chloride) (PVC) and poly(N-vinylpyrrolidone) (PVP) blends was investigated using potentiometric measurements of the released HCl gas during the degradation process, estimating the degree of discoloration of the degraded samples and measuring the thermal stability (Ts) values. The influence of the PVP percentage in the blend and, moreover, of the addition of commercial dibasic lead carbonate stabilizer to the blend was studied with regard to thermal stability. It turned out that the dehydrochlorination rate of the blend was promoted by increasing the PVP concentration in the blend.
