Abstract: Catalyst precursors comprising Mg, Cl, Ti, and OR groups that are in molar ratios defined by the formula MgClnTip(OR)(2-n)+4p in which n is from 0.3 to less than 1.7, p is lower than 0.6, the molar ratio (OR)/Cl is lower than 4 and R is Cl -C15 hydrocarbon groups. The said precursor, just upon activation with organo-Al compounds, are able to advantageously polymerize ethylene and alpha olefins, and that upon reaction with halogenating compounds generate in high yields catalyst components with high polymerization activity particularly in the polymerization of propylene also in combination with 1,3-diethers.
