    摘要: Catalytic component for the polymerization of ethylene with propylene prepared by:

    a) impregnation of an inert support with a solution of a compound of Vanadium having an oxidation state of between 3 and 5;
    b) subsequent treatment with a solution of a compound having general formula (I) R n AlX m wherein R is a C₁-C₂₀ alkyl radical, X is a halogen, n + m = 3 , and m is an integer between 0 and 2, the molar ratio between Aluminium in step (b) and Vanadium in step (a) being from 1/1 to 6/1.
