Abstract
A solid catalyst component for the polymerization of olefins made from or containing Mg, Ti and an electron donor of formula (I) wherein Rand Rgroups, equal to or different from each other, are selected from C-Chydrocarbon groups, Rgroup is selected from C-Chydrocarbon groups, and Rto Rgroups, independently, are selected from hydrogen or C-Chydrocarbon groups which can be fused together to form one or more cycles. The catalyst system based on the solid catalyst component is endowed with high activity and stereospecificity.
