Titanium trichloride catalytic component and process for the homo- or co-polymerization of alpha-olefins.

摘要

Preparation of titanium trichloride as compound of a Ziegler type catalyst by a process comprising the following steps:… first step: Reducing titanium tetrachloride with an organic aluminium compound… second step: treating the resulting reduced solid, which is obtained by the first step, with an organic ether compound… third step: reacting the treated solid, which is obtained by the second step, with titanium tetrachloride… and carrying out the reaction of the first step in a single solvent of an aromatic compound or a mixed solvent of an aliphatic hydrocarbon and an aromatic compound. …Use of this compound in the polymerization of alpha-olefins.
