Abstract:
A Prepolymerized catalyst component for the polymerization of olefins comprising a solid catalyst component which comprises Mg, Ti, and chlorine atoms and an electron donor (ID) said prepolymerized catalyst component being characterized by the fact that: the electron donor (ID) is constituted by at least 80% mol of 1,3 diethers with respect to the total molar amount of electron donor compounds; the prepolymerized catalyst has a porosity due to pores with diameters up to 1 μm of less than 0.2 cm3/g; it contains an amount of ethylene prepolymer of less than 45% with respect to the total weight of prepolymerized catalyst.

Claim (Index 11):
The prepolymerized catalyst component according to  claim 1 , wherein the (I) is selected among 1,3-diethers of formula (III): where the R III  and R IV  radicals have the same meaning defined in formula (I), R VI  radicals equal or different are hydrogen; halogens, selected from C 1 -C 20  alkyl radicals, linear or branched; C 3 -C 20  cycloalkyl, C 6 -C 20  aryl, C 7 -C 20  alkylaryl and C 7 -C 20  aralkyl radicals, optionally containing one or more heteroatoms selected from the group consisting of N, O, S, P, Si and halogens, in particular Cl and F, as substitutes for carbon or hydrogen atoms, or both.
