    • The invention relates to a novel process for the preparation of an olefin polymerization catalyst component comprising magnesium, titanium, a halogen and an electron donor. The process comprises the steps of: (i) reacting a titaniumless magnesium compound (a) containing an alkoxy moiety, which titaniumless magnesium compound is selected from the group consisting of a compound or complex containing halogen and alkoxy linked to magnesium, a complex containing a magnesium dihalide and an alcohol, and a non-complex magnesium dialkoxide, with a halogen compound (b) being capable of forming the electron donor by replacement of its halogen by said alkoxy moiety, to give an intermediate (ab), and (ii) reacting said intermediate (ab) with a titanium halide (c), or (i)′ reacting a titaniumless magnesium compound (a) containing an alkoxy moiety, which titaniumless magnesium compound is selected from the group consisting of a compound or complex containing halogen and alkoxy linked to magnesium, and a complex containing a magnesium dihalide and an alcohol, with a titanium halide (c), to give an intermediate (ac), and (ii)′ reacting said intermediate (ac) with a halogen compound (b) being capable of forming the electron donor by replacement of its halogen by said alkoxy moiety.

    • In the polymerization of C3-C12-&agr;-olefins, the activity of the catalyst and the isotacticity and molecular weight of the polymer product can be adjusted and improved in a controlled manner by a new process wherein A) a catalyst system is prepared by bringing a support which comprises magnesium chloride, a derivative thereof or a reagent forming it into contact with at least titanium tetrachloride or a reagent forming it, in order to produce a titanated support; by bringing the titanated support into contact with at least a group 1, 2 or 13 metal compound which contains a C1-C10-alkyl and activates titanium tetrachloride to a catalytically active titanium group, in order to produce an activated support; and by bringing a substance selected from among the said support, titanated support and activated support into contact with at least one donor or a reagent forming it, in order to produce a catalyst system B) polymerization is carried out using the catalyst system by bringing it into contact with at least a C3-C12-&agr;-olefin, whereupon poly-C3-C12-&agr;-olefin chains are formed in the catalytically active titanium groups, and preferably by bringing the said catalyst system, the said C3-C12-&agr;-olefin and the said poly-C3-C12-&agr;-olefin chains into contact with hydrogen or some other similar chain transfer agent, whereupon a poly-C3-C12-&agr;-olefin terminated with hydrogen or suchlike is formed. In the process the improvement is achieved so that, in step A), i) a first controlled amount of a less soluble internal donor and a second controlled amount of a more soluble internal donor are provided on the surface of the said support, titanated support or activated support, in order to produce an internal donoration product, and ii) the internal donoration product is brought into contact with at least one eluant eluting the more soluble internal donor and with at least one external donor or a reagent forming it, in order to produce an external donoration product, the catalyst system thereby formed having at least catalytically active titanium groups, the said first controlled amount of the less soluble internal donor and the said second controlled amount comprising external donor.

    • The present invention relates to a procatalyst composition for the polymerization of alpha-olefines, which has been prepared in steps, in which is arranged a carrier agent based on at least one inorganic oxide, having few or no hydroxyl groups on its surface, and the carier agent is reacted with the magnesium compound and one or more transition metal compounds of the groups IVB and VB of the periodic table. It has been observed that such a catalyst is most-advantageous when a) this carrier agent is impregnated with a mixture of the Mg compound and one or more compounds of a transition metal of the groups IVb or Vb of the periodic table, which dissolves the Mg compound, and b) by chlorinating with a compound that does not contain titanium so that 1) the carrier is first treated with a mixture in the form of a solution of the Mg compound and the transition metal compound and the product thus obtained is chlorinated, or 2) the carrier is first chlorinated and subsequently treated with the above mixture in the form of a solution, or 3) the Mg compound and the transition metal compound are impregnated into the carrier without any separate dissolving and the product thus obtained is chlorinated.
