Abstract
Catalyst component for the polymerization of olefins comprising Mg, Ti and an electron donor of formula (I) In which X and Y are selected from, R1, and —OR1 and —NR2, B is oxygen or sulphur S is sulphur, R1 is selected from C1-C15 hydrocarbon groups, optionally contain a heteroatom selected from halogen, P, S, N, O and Si, which can be fused together to form one or more cycles, R is hydrogen or R1 and A is a bivalent bridging group with chain length between the two bridging bonds being 1-10 atoms.

A solid catalyst component for the polymerization of olefins comprising Mg, Ti, Cl and at least an electron donor compound of formula (II)
- in which B is oxygen or sulphur S is sulfur, R4-R7 groups, equal to or different from each other, are hydrogen or C1-C15 hydrocarbon groups, optionally containing an heteroatom selected from halogen, P, S, N and Si, and R8, equal to or different from each other, are selected from C1-C15 hydrocarbon groups which can be optionally linked to form a cycle and n is an integer from 0 to 5.
