Polymerization catalysts, particularly catalysts for the polymerization of olefins, are disclosed. The catalysts are prepared by mixing

Polymerization catalysts

There are disclosed catalysts which are highly active in the polymerization of olefins and which are prepared by mixing hydrides or organometallic compounds of metals belonging to Groups I to III of the Mendelyeev Periodic Table with the product of reaction between an organic magnesium halide and a halogenated titanium compound, said reaction product containing titanium in an amount of from 0.05% to 10% by weight. Methods for preparing the aforesaid catalysts and the use of the catalysts in the polymerization of ethylene and mixtures thereof with higher alpha-olefins and/or diolefins are also disclosed.
