Process for olefin polymerization

Abstract

The present application provides a process for polymerizing at least one olefin in the presence of a polymerization catalyst, including: (A) continuously introducing a first liquid with a transition metal compound, an organometallic compound, and a solvent and a second liquid into an emulsification stage, (B) continuously withdrawing the emulsion and directing it into a solidification stage to form a slurry with a solid polymerization catalyst component, (C) continuously recovering the solid polymerization catalyst component, (D) directing the solid polymerization catalyst component into a first prepolymerization stage with a monomer and a second liquid to form a slurry, (E) recovering a prepolymerized solid polymerization catalyst component, (F) continuously introducing the prepolymerized solid polymerization catalyst component into a second prepolymerization stage with an olefin monomer to form a prepolymerized catalyst, and (G) continuously withdrawing the prepolymerized catalyst and directing it into a subsequent polymerization stage with at least one olefin monomer.
