Case 5105 ABSTRACT OF THE DISCLOSURE A supported Ziegler catalyst component prepared by (A) reacting a refractory oxide support material having surface -OH groups, for example silica, with halogen-containing transition metal compound, eg titanium tetrachloride, (B) reacting the product with an organometallic compound, for example triethyl aluminium and (C) reacting with transition metal compound in which vanadium is present, for example vanadyl chloride. The catalyst component is conventionally activated with organometallic compound and can be used to polymerise 1-olefins, for example ethylene.
