Abstract: The present technology relates to a solid catalyst component for the polymerization of olefins comprising Mg, Ti and an electron donor of the general formula (I): where R1 is selected from C1-C15 hydrocarbon groups, the R2 groups are equal to or different from each other, are hydrogen, or the R1 groups can be fused together to form one or more cycles and A is a bivalent bridging group. The catalyst components of the present disclosure exhibit high activity and stereospecificity in the polymerization of olefins.
