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.

Abstract: A catalyst component for the polymerization of olefins comprising Mg, Ti and at least two electron donor compounds, one of which (A) belonging to specific diolesters and the other electron donor compound (B) being selected from aromatic monoesters of the following formula (B) in which R groups equal to or different from each other, are selected from C1-C15 hydrocarbon groups which can be also linked to form one or more cycles, m is an integer from 1 to 5 and R5 is a C1-C15 alkyl group, said electron donors A and B being in amounts such that the A/B molar ratio is lower than 20.

Abstract: where each Q is a group —COOR1, in which R1 is selected from C1-C15 hydrocarbon groups, optionally containing a heteroatom selected from the group consisting of halogens, P, S, N and O; or a group —CON(R2)2, in which R2 groups, equal to or different from each other, are hydrogen or R1 groups which can be fused together to form one or more cycles, and A is a bivalent bridging group with the proviso that the Q groups cannot be simultaneously a group —COOR1 or —CON(R2)2.
