Abstract: A catalyst component comprising Ti, Mg, Cl, and optionally OR1 groups in which R1 is a C1- C20 hydrocarbon group up to an amount such as to give a molar ORI/Ti ratio lower than 0.5, characterized by the following properties: surface area, determined by BET method, of lower than 80 m2/g, - a total porosity (PT), measured by the mercury method, in the range of 0.60-1.50 cm3/g - - a difference (PT-PF) of higher than 0.1 in which PT is the total porosity and PF is the porosity due to pore with radius equal to or less than 1 μm; - an amount of Ti in the catalyst component of less that 10 %wt based on the total weight of catalyst component. The said catalyst components show high morphological stability under the low molecular weight ethylene polymerization conditions while at the same time maintaining characteristics of high activity.

Abstract: Catalyst components for the polymerization of olefins CH2=CHR, wherein R is hydrogen or a hydrocarbon radical having 1-12 carbon atoms, comprising Mg, Ti, C1, OR groups, where R is a C1-C10 alkyl group optionally containing heteroatoms, and an ether having two or more ether groups, characterized by the fact that the Mg/Ti weight ratio is lower than 3 from 2 to 6.5 the C1/Ti weight ratio is from 1.5 to 6, the OR/Ti weight ratio is from 0.5 to 3.5 and at least 50% of the Titanium atoms are in a valence state lower than 4. The said catalyst components allow the preparation of ethylene copolymers with a low content of xylene soluble fractions.

Abstract: Lewis base adducts comprising MgCln(OR)2-n, and an aprotic Lewis base that are in molar ratios to each other defined by the formula: MgCln(OR)2-nLBp in which n is from 0.1 to 1.9, p is higher than 0.4, and R is a C1-C15 hydrocarbon group. The adducts of the present invention are particularly useful as precursors of Ziegler-Natta catalyst components for the polymerization of olefins.
