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.
