Beschreibung
Zusammenfassung:	The present invention provides a Ziegler-Natta catalyst for olefin polymerization comprising transition metal compound containing aryloxy ligand and transition metal with the oxidation number of 3 from Group IV, V or VI of the Periodic Table of Elements which is prepared by the reduction of transition metal compound containing at least two aryloxy ligands and transition metal with the oxidation number of 4 or more from Group IV, V or VI of the Periodic Table, and an olefin (co)polymerization method using the same as a main catalyst. According to the present invention, it is possible to provide a Ziegler-Natta catalyst for olefin polymerization having high polymerization activity, as compared with conventional catalysts of transition metal compounds comprising transition metal compound containing transition metal with the oxidation number of 3, and a method for preparing olefin (co)polymer having broad molecular weight distribution by using the same with high activity.
