Abstract

1. Catalysts for polymerization of alpha-alkenes, which contain at least 3 carbon atoms, and mixtures of these with ethylene, characterized in that they contain the product which is produced by making contact among the following compounds serving as starting materials: a) an organometal aluminum compound, which is free of halogen atoms that are directly bound to the aluminum atom, b) an electron donor compound, such as a Lewis base, in such an amount that between 15 and 100 per cent of the organometal aluminum compound is combined with the electron donor compound, c) a solid component which at least on the surface contains the reaction product between a halogenated Mg compound and a tetravalent Ti compound and with an electron donor compound, wherein the molar ratio of electron donor to Ti in the product is higher than 0.2, and wherein the ratio between halogen atoms and Ti is higher than 4, and wherein the product is further characterized in that at least 80 per cent by weight of the tetravalent Ti compounds located therein are insoluble in boiling n-heptane, and at least 50 per cent by weight of the Ti compounds that are insoluble in n- heptane are also insoluble in TiCl4 at 80 degrees Celsius, and the surface area of the product which is insoluble in TiCl4 at 80 degrees Celsius and the surface area of component c) as such is greater than 40 m2/g.
