Production of Ziegler-Natta catalysts

摘要

A process for producing a Ziegler-Natta catalyst, the process comprising reacting an organo magnesium compound with a halogenated compound to produce crystalline magnesium halide and titanating the magnesium halide by mixing the magnesium halide with a titanium compound whereby the titanated magnesium halide has, in an x-ray spectrum thereof, a halo appearing at a lattice distance within the range from 2.56 to 2.95 Angstroms.
