  • Catalytic titanium compound, process for the manufacture thereof, and method for the polymerization of alkenes-1 with application of such a titanium component
    Patent number: 4670525
    Abstract: The invention relates to a catalytic titanium component useful for the polymerization of alkenes-1 and for the copolymerization of alkenes-1 with each other or with ethylene, containing a halogenated titanium compound, an electron donor, and a metal halide obtained by conversion of an organic metal compound with a halogenating agent of the formula RX.sub.m, wherein R is a hydrocarbon group, a hydrogen atom or a halogen atom, X is a halogen atom, and m is a whole number from 1-10. The catalytic titanium component according to the invention is characterized in that the metal halide has been obtained by conversion of a combination of an organic aluminium compound and an organic magnesium compound with the halogenating agent into the corresponding metal halide, for instance by means of a reaction with hydrogen chloride or an alkyl chloride.
