摘要：

With the aid of a differential scanning calorimeter (DSC), the non-isothermal crystallization kinetics of polypropylene was investigated on the basis of the Avrami equation, Turnbull-Fisher nucleation theory and Hoffman-Lauritzen growth theory. According to the non-isothermal crystallization kinetics derived from the isothermal cases, it is revealed that the ultimate crystallinity and the average ultimate spherulite size increase to finite values as the cooling rate decreases, while the average ultimate spherulite number varies in the opposite sense.
