  • Publication number: 20060247123
    Abstract: A method of making a hydrocarbon oil dispersion of a solid procatalyst for use in a Ziegler-Natta olefin polymerization catalyst composition, said method comprising: preparing and recovering a procatalyst composition in the form of a solid mass containing residual liquid rinse diluant, partially drying the solid procatalyst composition to provide a residual liquid rinse diluent content of from 7 to 25 percent, and dispersing the partially dried, solid precursor composition in a hydrocarbon oil.
    Type: Application

  • Publication number: 20050054792
    Abstract: A method of making a solid procatalyst composition for use in a Ziegler-Natta olefin polymerization catalyst composition, said method comprising: contacting a solid precursor composition comprising magnesium, titanium, and alkoxide moieties with a titanium halide compound and an internal electron donor in any order, in a suitable reaction medium to prepare a solid procatalyst composition, separating the solid procatalyst from the reaction medium, further exchanging residual alkoxide functionality of the solid procatalyst composition for chloride functionality by contacting the same two or more times with benzoyl chloride halogenating agent under metathesis conditions for a period of time sufficient to prepare a solid procatalyst composition having a decreased alkoxide content compared to the alkoxide content of the solid procatalyst composition before said exchange, and recovering the solid procatalyst composition.
