Sažetak
The process of thermooxidative degradation of poly (vinyl chloride)/(methyl methacrylate-butadiene-styrene) (PVC/MBS) blends was investigated by means of nonisothermal thermogravimetry in air. Measurements were carried out in the temperature range of 50-650°C. The kinetic parameters (Ea and A) of the first degradation step were determined by applying Flynn-Wall-Ozawa method. Their relationship through compensation effect was discussed and the apparent compensation effect was found. The addition of MBS changes the rate of PVC dehydroclorination in the blends, while in the blends with 15 and more MBS ratio, the reaction scheme of degradation changes too.
