Abstract

Catalyst component for the polymerization of olefins comprising Mg, Ti and an electron donor compound of the following formula (I)In whichR to R4 groups, equal to or different from each other, are hydrogen, halogen or C1-C15 hydrocarbon groups, optionally containing an heteroatom selected from halogen, P, S, N and Si, which may be linked to form a saturated or unsaturated mono or polycycle and R5 groups are selected from C1-C15 hydrocarbon groups optionally containing an heteroatom selected from halogen, P, S, N and Si.
