    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.
