Abstract:
1. A system for introduction of multiple components into a polymerization system, comprising: a polymerization catalyst component; an activator compound component; a co-catalyst component; a diluent; means for adding the polymerization catalyst component into the polymerization system at a controlled rate; means for adding the activator compound component into the polymerization system at a controlled rate; means for adding the co-catalyst component into the polymerization system at a controlled rate; means for adding the diluent into the polymerization system at a controlled rate; means for introducing the polymerization catalyst component, the activator compound component, the co-catalyst component, and the diluent into a pre-contactor; means for agitating the polymerization catalyst component, the activator compound component, the co-catalyst component, and the diluent in the pre-contactor; means for directing output from the pre-contactor to a polymerization reactor; and wherein the pre-contactor is configured to receive a first portion of the activator compound component, and the polymerization reactor is configured to receive a second portion of the activator compound component, wherein the second portion was not sent to the pre-contactor.
