Polymerization or propylene was carried out under bulk process at 70℃ using the supported metallocene catalyst with four kinds of SiO₂ as carrier with triethylaluminum used as co-catalyst. The morphology of the products was studied by SEM. It was found the property of the carriers gave great effect on the fine structure of the products as well as the apperance.
