Abstract
The present disclosure relates to a catalyst component for the polymerization of olefins comprising Mg. Ti and an electron donor such as mercaptoester derivatives of the general formula (I). in which Z is selected from C, Si, O, N, S or P, with the proviso that the atoms O, S, P and N are not directly linked to either the carboxylic group or the sulfur atom of formula (I), the Rgroups, equal to or different from each other, are selected from hydrogen or a C-Chydrocarbon radicals, optionally containing a heteroatom selected from halogen, P, S, N, O and Si, which can be fused together to form one or more cycles, m is a number satisfying the valences of Z and n is an integer ranging from 1 to 10, X is O or S, Y is —OR, —NRR) or Rgroups in which Rand Rare selected from C-Chydrocarbon groups, optionally containing a heteroatom selected from halogen, P, S, N, O, and Si, R-Rgroups, independently, are hydrogen or Rgroups, and Rgroups have the same composition as Rgroups.
