Abstract
Official abstract text for this publication.
Multiple components are selected, conveyed, and measured in a polymerization system. A control system adjusts the system variables to the desired values. Portions of the components can be fed to a pre-contactor before introduction into the polymerization reactor. The catalyst component concentrations and residence times are tightly controlled in the pre-contactor to affect product properties. The pre-contactor can be a single or multiple combinations of a CSTR or plug flow pre-contactors.
First claim
Opening claim text (preview).
The invention claimed is: 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 com…
