Disclosed is a polymetallic supported catalyst component comprising an activated anhydrous MgCl2 solid support which has been treated with at least one treatment of at least two halogen-containing transition-metal compounds, wherein one is a halogen-containing titanium metal compound and one is a halogen-containing non-titanium transition metal compound, optionally, in the presence of an electron donor and the processes for producing the component. A catalyst for the polymerization of at least one alpha-olefin of the formula CH2-CHR, where R is H or a C1-12 branched or straight chain alkyl or substituted or unsubstituted cycloalkyl, by reacting this supported catalyst component with an organometallic cocatalyst, optionally in the presence of an electron donor, and the polymerization of at least one alpha-olefin with the catalyst are also disclosed. The resulting polymers, particularly propylene polymers, have a controllable atactic content, which is expressed herein in terms of its xylene solubility at room temperature (XSRT), wherein the ratio of the I.V. of the XSRT fraction to the I.V. of the bulk polymer is greater than or equal to 0.50.
