| Abstract: | The nonisothermal crystallization processes of polypropylene(PP) and polypropylene/poly(propylene g maleic anhydride)(PP g MAH)/organo montmorillonite(Org MMT) have been investigated by DSC. The Avrami and Ozawa equations were used to describe the nonisothermal crystallization processes of the above systems. The parameter values of t 1/2 ? Z c? F(T) ? T p indicated that at the same cooling rate the crystallization rate of PP/PP g MAH/Org MMT composite was greater than that of PP and that the crystallization temperature of the former was higher than that of the latter. The activation energies of PP and composites calculated by Kissinger method revealed that the addition of Org MMT in PP increased the activation energy of PP, however, the addition of PP g MAH in PP/Org MMT composite decreased its activation energy, even close to that of pure PP. |
