摘要： Polymerization of ethylene or .alpha.-olefins using a catalyst comprising a titanium component obtained by copulverizing the starting titanium component of Ziegler catalysts and organoaluminum compound with a small amount of ethylene or .alpha.-olefins, and an organoaluminum component. The titanium catalyst component can be modified by subjecting the copulverized titanium component to a contact with an inert organic solvent or its mixture with a modifier (1) an oxygen-, sulphur-, phosphor-, nitrogen- or silicon- containing organic compound, (2) a combination of such an organic compound and an aluminum halide, (3) an organoaluminum compound or (4) a Lewis acid.
