Abstract:
1. A solid catalytic component comprising a titanium or vanadium compound, a compound of magnesium containing at least one halogen, a particulate porous support, and optionally an internal electron donor, wherein the solid catalytic component is prepared by using a process comprising a step of contacting the particulate porous support with a solution of an hydrocarbon soluble organomagnesium compound in a hydrocarbon solvent, which solution of a hydrocarbon soluble organomagnesium compound is contacted with a coordinating electron donor compound in a molar ratio of coordinating donor compound to organomagnesium compound ranging from 0.1:1 to 5:1, the process of preparing the solid catalytic component further comprising a step of converting the organomagnesium compound into a compound of magnesium containing at least one halogen.
