Abstract : Polypropylene (PP) nanocomposites were prepared by incorporating multiwalled carbon nanotubes (MWCNTs) at different contents from 1 to 4 wt%. The crystallization studies were performed using differential scanning calorimetry (DSC) at varying cooling rates viz. 5, 10, 15 and 20 °C/min. The Avrami model could describe the intermediate stages of crystallization quite well whereas the Ozawa model failed to explain the kinetics particularly in the region of peak crystallization temperatures. Mo model could very well describe the nucleation, crystal growth and the crystal impingement which was verified from the linearity obtained by the model equation and from the Mo parameters
