Abstract
The present disclosure relates to a solid catalyst component for the polymerization of olefins comprising Mg, Ti and an electron donor of the formula (I): 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.
