Abstract
With the aid of differential scanning calorimetry (DSC), we first analyzed the isothermal crystallization kinetics of polypropylene (PP) on the basis of the Avrami equation, the Turnbull-Fisher nucleation theory and the Hoffman-Lauritzen growth theory. It is shown that the nucleation rate, the average radial growth rate of spherulites and the overall crystallization rate constant first increase and then decrease as the supercooling temperature increases. © 1993.
