Plastic material for packaging

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 magnesium 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

Method of polmerizing olefines

A catalyst component for polymerization catalyst of .alpha.-olefines, the polymerization catalyst comprising an organoaluminum compound, an electron donor, as well as the solid catalyst component which is obtained when a compound containing magnesium reacts with a titanium halogen compound. A method for producing the catalyst component 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

Catalyst components for polymerization catalyst of olefins and method

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

Catalysts for polymerizing olefines and method for the preparation

Catalysts for polymerization and copolymerization of olefins to form polymers having a high degree of isotacticity and fast rate of crystal transformation. The catalysts embody a component made by chlorinating a magnesium alkyl with chlorine or a mixture of chlorine and alkyl chloride to form a carrier, contacting the carrier first with liquid TiCl.sub.4, then with a Lewis base, and after that at least once with TiCl.sub.4 in the absence of Lewis base.
