Abstract
A solid catalyst component for the polymerization of olefins made from or containing Mg, Ti and an electron donor of formula (I) where the R1 and R5 groups, equal to or different from each other, are selected from C1-C15 hydrocarbon groups, R2 group is selected from C2-C10 hydrocarbon groups, R3 to R4 groups, independently, are selected from hydrogen or C1-C20 hydrocarbon groups, optionally fused together to form one or more cycles, with the proviso that at least one of R3 to R4 groups is a C1-C20 alkyl group.
