摘要： Solid catalysts which can be used for the polymerization of olefins, essentially comprising compounds of magnesium and metals selected from the transition metals of sub-groups IVa, Va and VIa of the periodic table of elements, said catalysts being produced in accordance with a method which comprises in a first stage the preparation of a solid compound of magnesium and a transition metal by the reaction of organo-magnesium compounds, monohalogenated hydrocarbons and halogenated and/or organic derivatives of said transition metal taken in a state of valency at least equal to four, then, in a second stage, bringing the solid magnesium and transition metal compound resulting from the preceding reaction into contact with an oxidizing compound.
