PREPOLYMERIZED CATALYST FOR OLEFIN POLYMERIZATION AND METHOD OF PREPARATION OF POLYOLEFIN USING THE SAME

摘要

PURPOSE: A prepolymerized catalyst for olefin polymerization is provided to improve various properties with high cycle property in rigidity, transparency and injection molding while not damaging unique property of polyolefin. CONSTITUTION: A prepolymerized catalyst for olefin polymerization is formed by prepolymerizing a styrenic monomer on the surface of Ziegler-Natta catalyst particles. The Ziegler-Natta catalyst particles comprise transition metal compound containing Group 4-6 element as a main catalyst component and an organometallic compound containing Group 13 elements as a cocatalyst component.
