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).
