	通过动态硫化方法制备了聚丙烯/三元乙丙橡胶(PP/EPDM)共混体系，研究了不同橡塑比、SiO2添加量等因素对PP/EPDM共混体系的力学性能、导热及结晶动力学的影响。研究表明，随着EPDM含量增加，共混物冷却速率较纯PP有显著提高；随着EPDM的加入，使得PP半晶时间(t1/2)显著缩短，EPDM在共混体系的冷却结晶过程中对PP具有良好的成核促进作用。&lt;br/&gt;The PP/EPDM blends were prepared using dynamical vulcanization. The effects of different plas-tic/rubber ratios, content of SiO2 on the mechanical properties, thermal conductivity as well as crystallization kinetics were intensively investigated. Our findings showed that the cooling rate of the PP/EPDM blends increased with increasing EPDM content. With the addition of EPDM, the crystallization half time (t1/2) was shortened, suggesting that the existence of EPDM phase was fa-vorable to the improvement on PP nucleation during the cooling period from melt state.
