%X SiO2/rac-Me2Si2-Me-4-Naph-Ind]2ZrCl2 was prepared and different co-catalysts were used in bulk polymerization of propene. The morphology of polypropene could be controlled by altering the co-catalysts. The isotactic polypropene with good morphology and high bulk density were prepared. The formation mechanism of active centers was proposed, by which the effect of co-catalysts on the morphology of polypeopene was analyzed.
