- 19 - Abstract of the Disclosure: Homopolymers and copolymers of ethene are prepared using a Ziegler catalyst system comprising (1) a transition metal catalyst component, (2) an organoaluminum catalyst component and (3) an organo- halogen catalyst component, by a method in which the transition metal catalyst component (1) employed is a solid-phase product (VI) obtained by (1.1) first combin- ing (1.1.1) an inorganic oxidic substance ((I), as the car- rier, with (1.1.2) a solution (II) consisting of (IIa) a certain oxahydrocarbon and (IIb) a mixture of (IIb1) a vanadium trichloride/alcohol complex, (IIb2) a titanium trihalide or titanium trihalide/alcohol complex and, if required, (IIb3) a zirconium tetrahalide to form a sus- pension (III), evaporating down this suspension to form a solid-phase intermediate (IV), and (1.2) then (1.2.1) combining the solid-phase intermediate (IV) obtained from (1.1) with (1.2.2) a solution of an organoaluminum com- pound (V) to form a suspension, the resulting suspended solid-phase product (VI) being the transition metal cata- lyst component (1).
