ABSTRACT:
Catalyst for polymerization of .alpha.-olefines, comprising an organoaluminum compound, an electron donor, as well as a solid catalyst component which is obtained when a compound containing magensium reacts with a titanium halogen compound. A method for producing the catalyst is also provided. The catalyst component is manufactured by reacting with a titanium halogen compound in the presence of an internal electron donor, a solid catalyst component which has been produced by the steps of
