Abstract: | Summary The MgCl2 supported TiCl3 catalyst was prepared by grinding the mixture of TiCl3·3Py and MgCl2 in a ball mill. The catalyst was treated either i.vac. at 50–200°C or with alkylaluminum halides to remove the residual pyridine, and propylene polymerization was conducted at 65°C using the resulting catalysts combined with triethylaluminum. The catalyst treated with diethylaluminum chloride showed an extremely high activity for the polymerization. |
