  • Substantially agglomeration-free catalyst component
    Patent number: 4444967
    Abstract: A substantially agglomeration-free, finely divided catalyst component which is suitable for use as a cocatalyst with organoaluminum compounds in the polymerization of alpha olefins, which is formed by grinding a titanium trichloride material, an effective amount of an electron pair donor compound to enhance the performance of said catalyst component, and an effective amount for agglomeration control of an agglomeration control agent. The agglomeration control agent is effective in either reducing the attractive forces between the finely divided particles in the catalyst component or by preventing the close approach of these particles which would result in agglomeration.
    Type: Grant
    Filed: March 21, 1983
    Date of Patent: April 24, 1984
    Assignee: Stauffer Chemical Company
    Inventors: Gregory G. Arzoumanidis, Richard F. Gold, Christian G. Michel
