  • Polymerization process
    Publication number: 20020107342
    Abstract: The invention provides for polymerization catalyst compositions, and for methods for introducing the catalyst compositions into a polymerization reactor. More particularly, the method combines a catalyst component containing slurry and a catalyst component containing solution to form the completed catalyst composition for introduction into the polymerization reactor. The invention is also directed to methods of preparing the catalyst component slurry, the catalyst component solution and the catalyst compositions, to methods of controlling the properties of polymer products utilizing the catalyst compositions, and to polymers produced therefrom.

  • Manufacture of stereoregular polymers
    Patent number: 6211310
    Abstract: The present invention teaches the use of particular soluble metallocene catalysts to produce stereoregular polymers in gas phase polymerizations wherein the catalysts are fed into a particular lean zone in the reactor. The metallocene catalysts are bridged bis(substituted indenyl) compounds.

  • Spray dried, filled metallocene catalyst composition for use in polyolefin manufacture
    Patent number: 5674795
    Abstract: Metallocene-containing catalyst compositions that include inert filler, a method for their preparation, and a method for their use in production of polyolefins are disclosed and claimed. The catalyst compositions contain solid particles of a mixture comprising a) a metallocene catalyst; b) a cocatalyst capable of activating said metallocene catalyst; and c) particulate filler material having an average particle size of less than about 10 micrometers that is unreactive with the metallocene catalyst and the cocatalyst. They are prepared by spray drying a slurry of the constituents.
