| Abstract: | Non-isothermal crystallization kinetics of isotactic polypropylene (iPP) in soybean oil were investigated via differential scanning calorimetry (DSC) . The crystal structure of iPP in soybean oil was observed using scanning electron microscopy (SEM). Non-isothermal crystallization kinetic parameters,such as Avrami exponent, crystallization constant and kinetic crystallizability ect. , were obtained using Ziabicki theory and Jeziorny method. The effect of iPP initial concentration and cooling rate on kinetic parameters were also discussed. |
