Abstract

The kinetics of the thermal-oxidative decomposition of polypropylene (PP) was studied by a conventional thermogravimetric technique in pure nitrogen and various concentrations of oxygen ranging from 5-21%. The kinetic model that accounts for the effects of oxygen concentration was proposed to describe the thermal decomposition of PP. The thermogravimetric analysis curve and its derivative have been analyzed using the differential and integral methods with modification of the Friedman and Coats-Redfern methods. The activation energy, the pre-exponential factor, and the reaction order for unreacted material and oxygen concentration have been determined. When oxygen was present, the activation energy was reduced significantly.
