    Abstract: A solid catalyst component for the polymerization of olefins CH2═CHR in which R is hydrogen or a hydrocarbon radical with 1-12 carbon atoms, made from or containing Mg, Ti, Bi, halogen and an electron donor obtained from a process including the steps:
    (a) dissolving a Mg(OR)2 compound wherein R groups, equal to or different from each other, are C1-C15 hydrocarbon groups optionally containing a heteroatom selected from O, N and halogen, in an organic liquid medium, thereby forming a first liquid mixture;
    (b) contacting the first liquid mixture (a) with TiCl4, thereby forming a second liquid mixture absent a solid phase, and
    (c) subjecting the second liquid mixture (b) to conditions, whereby solid catalyst particles are formed,
    wherein (i) a Bi compound and (ii) a bidentate electron donor compound are present in one or more of steps (a) to (c) and/or contacted with the solid catalyst particles obtained from (c).

    Abstract: A catalyst for the homopolymerization or copolymerization of CH2═CHR olefins, made from or containing the product obtained by contacting: (i) a solid catalyst component made from or containing Ti, Mg, Cl, and an internal electron donor compound, wherein the solid catalyst component contains from about 0.1 to about 50 wt % of Bi, based upon the total weight of the solid catalyst component; (ii) an alkyl aluminum compound and, (iii) an external electron donor compound having the formula: (R1)aSi(OR2)b wherein R1 and R2 are independently selected from the group consisting of alkyl radicals with 1-8 carbon atoms and a is 0 or 1 and a+b=4.
