Patent ID: 7615596

Claim:
A method for introduction of multiple components into a polymerization system, comprising the steps of: adding at least one polymerization catalyst component into the polymerization system at a controlled rate; adding at least one activator compound component into the polymerization system at a controlled rate; adding at least one co-catalyst component into the polymerization system at a controlled rate; introducing a portion of at least one of the components in at least one pre-contactor; directing output from the pre contactor to at least one polymerization reactor; and directing remaining portions of the components that were not sent to the pre-contactor to the at least one polymerization reactor; wherein the step of adding the components into the polymerization system at a controlled rate comprises the steps of: selecting a desired flow rate for each component; conveying each component into the polymerization system at an actual flow rate; measuring the actual flow rate for each component; and adjusting the actual flow rate for each component to substantially equal the desired flow rate.
