    摘要: The present invention relates to a MgCl2.mEtOH adduct in which m is from 2.5 to 3.2 optionally containing water up to a maximum of 1% wt based on the total weight of the adduct, characterized by a DSC profile in which the highest melting Temperature (Tm) peak is over 109° C. and has an associated fusion enthalpy ( H) of 103 J/g or lower. Catalyst components obtained from the adducts of the present invention are capable to give catalysts for the polymerization of olefins characterized by enhanced activity with respect to the catalysts prepared from the adducts of the prior art.
