    Abstract: A process for preparing a solid catalyst component for the homopolymerization or copolymerization of CH2═CHR olefins, wherein R is hydrogen or hydrocarbyl radical with 1-12 carbon atoms, including a step (a), at a temperature ranging from 0 to 150° C., of reacting a Mg based compound of formula (MgClmX2-m).nLB, wherein m ranges from 0 to 2, n ranges from 0 to 6, X is, independently R1, OR1, —OCOR1 or O—C(O)—OR1 group, wherein R1 is a C1-C20 hydrocarbon group and LB is a Lewis base with a liquid medium made from or containing a Ti compound, having a Ti—Cl bond, in an amount such that the Ti/Mg molar ratio is higher than 3 and a Bi compound dissolved or dispersed in the liquid medium, wherein the solid catalyst compound is made from or contains the Ti compound, the Bi compound and optionally an electron donor on a Mg chloride based support.

    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.
