Abstract
The thermogravimetric method is used to study the degradation of polypropylene (PP), mixed polyamide PA6/66 (PA), and their mixtures with PA contents of 10 and 40 wt.% in the temperature range from 30 to 700 °C in air. A significant inhibitory effect of PA on PP degradation is discovered. The maximum decomposition temperatures of mixtures in the presence of polyamide increase by more than 50 °C. This effect is comparable to the inhibitory effect of known antioxidants. A mechanism of inhibitory action is proposed as a result of the reaction of the PA phase with the oxidation products and the PP radicals.
