<p>The present invention relates to a catalyst for preparing polyolefin and olefin polymerization using the same, particularly to a method for preparing polyolefin using a compound obtained by activating metalloenamine compound with Lewis acid as a catalyst. Metalloenamine compound having C=C-N-M basic structure is reacted with various Lewis acid (A) to provide zwitterions compound having structure of -A-C-C=N-M+ because a-carbon therein has high nucleophilicity. At this time, a metal has cationic property and thus the compound shows activity for olefin polymerization. The obtained catalyst can be used for various olefin polymerizations.</p> |
