Abstract: A non-metallocene catalyst supported on a magnesium compound is disclosed. The catalyst is obtained either in situ through a supported method by directly contacting a non-metallocene ligand with a magnesium compound containing a metal with catalytic activity, or in situ through a supported method by directly contacting a metal compound with catalytic activity with a magnesium compound containing a non-metallocene ligand. In such methods the processes are industrially practicable, there are more adjustable parameters for the polymerization activity of catalyst, and the supported amount of the non-metallocene ligand and the polymerization activity of the catalyst can be adjusted in a wide range. In the case that the non-metallocene catalyst supported on the magnesium compound of this invention is combined with a cocatalyst to make an olefin polymerized, even if less cocatalsyt is used, high polymerization activity can be obtained. Also, the resulting polymer has high bulk density and its molecular weight distribution is adjustable.

Abstract: A supported non-metallocene catalyst which is obtained in situ through a supported method by reacting a non-metallocene ligand with a metal compound with catalytic activity on a carrier is disclosed. Such method is industrially practicable, and the supported amount of the non-metallocene ligand and the polymerization activity of the catalyst can be adjusted in a wide range. In the case that the supported non-metallocene catalyst is combined with a cocatalyst to make an olefin polymerized, even if less cocatalyst is used, high polymerization activity can be obtained. Also, the resulting polymer has good a particle shape and high bulk density.
