Abstract
By applying the experimental data described in Part I, the non-isothermal crystallization kinetics of isotactic polypropylene/ethylene-octene blends have been mathematically modeled. The commonly used Avrami, Ozawa, Mo and Urbanovici-Segal models were used to model the crystallization kinetics, and it appears that Mo and Urbanovici-Segal models can well describe the non-isothermal crystallization kinetics of PP/POE blends. The data processing indicates that a small amount of POE can enhance the kinetic crystallizability because of heterogeneous nucleation, but excessive POE would in turn reduce the kinetic crystallizability by blocking the crystallization of PP.
