Abstract
The present invention is directed to a process for producing a solid olefin polymerization catalyst component from an emulsion wherein the particle size of the solid catalyst or the droplet size of the emulsion is controlled. The actual size of the droplets or the solid catalyst particles is measured, or alternatively, both are measured. Then a difference between the actual size and the set point is calculated and the process is controlled based on the difference.
