ABSTRACT:
Catalyst precursors comprising Mg, Ti, OMe and OR groups that are in molar ratios defined by the formula MgTin(OMe)(p)(OR)xin which n is from 0.1 to 1, p is ≧(2+4n), x is from 0 to 1 and R is C2-C15 hydrocarbon groups can be easily transformed, with high yields, in solid catalyst components to be advantageously used in the polymerization of both ethylene and alpha olefins.
