Abstract: A solid catalyst component which exhibits high activity and stereospecificity in the polymerization of olefins made from or containing Mg, Ti and an electron donor of formula (I) where R and R1 are selected from the group consisting of C1-C20 hydrocarbon groups, C6-C14 aryl or alkylaryl groups hydrocarbon groups, optionally containing a heteroatom selected from the group consisting of halogens, P, S, N, and O; R2 to R11 groups, equal to or different from each other, are hydrogen, halogen or C1-C15 hydrocarbon groups which can be optionally fused together to form one or more cycles with the proviso that R6 and R11 cannot join together to form a phenyl ring.

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.
