This paper considers the possibility of raising the efficiency of thermal degradation of atactic polypropylene (APP) using existing industrial equipment in the presence of cumenyl peroxide (CP). It was found that the addition of CP in amounts from 0.1 to 1 mass % increases the rate and degree of APP degradiation substantially in the temperature range 200-300 degrees. The rate constants of thermal degradation were determined graphically from a kinetic equation for first-order reactions. The activation energy was 82.4 kJ/mole. In absence of peroxide the activation energy of thermal degradation of app is 217.4 kJ/mole. These results show that the addition of CP lowers the activation energy of thermal degradation of APP.
