摘要

The non-isothermal crystallization kinetics of the iPP/OIBS (octa-(iso-butyl) silsesquioxane) composites prepared by a twin extruder was studied by a differential scanning calorimetry (DSC). The crystallization parameters such as the peak temperature (T_p), starting crystallization temperature (T₀) and the width of half-height (W_1/2·h) were influenced by the concentration of OIBS. The changes of these parameters demonstrated that with a certain concentration of OIBS, the crystallization temperature of the samples might increase and the uniformity of crystal might improve, which show OIBS has a heterogeneous nucleation during non-isothermal crystallization process of iPP. The kinetics parameters were calculated by the modified Avrami theories of Jeziorny and Mozhishen, respectively. The Z_c and F(T) also indicated the crystallization rate could improved by a proper concentration of OIBS.
