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.
