Prepolymerization catalyst for olefin polymerization and preparation method of polyolefin using the same |
| abstract |
The present invention includes a transition metal compound containing an element belonging to Groups 4 to 6 of the periodic table as a main catalyst component, and a Ziegler-Natta catalyst particle comprising an organometallic compound containing a Group 13 element of the periodic table as a cocatalyst component. The present invention relates to a prepolymerization catalyst for olefin polymerization formed by prepolymerization of a styrene monomer on a surface of a polyolefin and a method for preparing polyolefin using the same. The styrene polymer prepolymerized on the surface of the Ziegler-Natta catalyst particles increases the crystallinity of the polyolefin. Thus, the polyolefin prepared using the prepolymerization catalyst according to the present invention is excellent in rigidity and impact resistance. |
