Abstract
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.
