| titleOfInvention | Preparation of homopolymers of ethene and copolymers of ethene with high α-monoolefins using a Ziegler catalyst system |
| abstract | The homopolymerization and copolymerization of ethene are carried out using a Ziegler catalyst system consisting of (1) a transition metal catalyst component, (2) an organoaluminum catalyst component and (3) an organohalogen catalyst component. In the homopolymerization or copolymerization, the solid-phase product (VI) used as (1) is the product which has been obtained by a method in which (1.1) first (1.1.1) an inorganic oxidic substance (I) as the carrier and (1.1.2) a solution (II) of (IIa) a certain oxahydrocarbon and (IIb) a vanadium trichloride/alcohol complex and (IIc) a silicon or boron compound are combined with formation of a suspension (III), the latter is evaporated down to form a solid-phase intermediate (IV), and (1.2) then (1.2.1) the intermediate (IV) obtained in (1.1) and (1.2.2) a dissolved organoaluminum compound (V) are combined with the formation of a suspension, the solid-phase product (VI) obtained as the suspended substance being the transition metal catalyst component (1). |
