Sažetak
The thermooxidative degradation of poly(vinyl chloride)/chlorinated polyethylene blends of different compositions was investigated by means of dynamic thermogravimetry in flowing atmosphere of synthetic air in temperature range 50 – 650 oC. Kinetic analysis was applied on the first basic degradation step (up to 400 oC) where the mean degradation processes are dehydrochlorination of PVC and CPE. For calculation of the apparent activation energy and apparent preexponential factor three kinetic methods were compared: integral Kissinger method, integral isoconversional Kissinger-Akahira-Sunose method and differential isoconversional Friedman method. The existence of the true or false compensation effect was discused
