Case 4823 ABSTRACT OF THE DISCLOSURE A supported Ziegler catalyst prepared by reacting, under substantially anhydrous conditions, a refractory oxide support material having acidic surface hydroxyl groups, eg silica, and an organo metallic compound, eg a trialkyl aluminium compound, separating any unreacted organo metallic compound and impregnating the solid product with a halogen-containing titanium compound and a halogen-containing vanadium compound. The catalyst, preferably together with a conventional Ziegler catalyst activator, eg an aluminium alkyl, is employed to polymerise 1-olefins, for example ethylene.
