ABSTRACT:
.alpha.-Monoolefins are polymerized using a Ziegler catalyst system comprising (1) a transition metal catalyst component and (2) an organoaluminum catalyst component, in which (1) is a solid-phase product (VI) obtained by (1.1) first combining (1.1.1) an inorganic oxidic substance (I), as the carrier, with (1.1.2) a solution (II) consisting of (IIa) an organic solvent and (IIb) a transition metal composition to form a suspension (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 compound (V) to form a suspension, the resulting suspended solid-phase product (VI) being the transition metal catalyst component (1). The characteristic feature is that (1) is a solid-phase product (VI) obtained using a solution (II) consisting of (IIa) a certain oxahydrocarbon and (IIb) a mixture of (IIb1) a vanadium trichloride/alcohol complex, (IIb2) a titanium trihalide and (IIb3) a zirconium tetrahalide.
