SUPPORTED NON-METALLOCENE CATALYST AND ITS PREPARATION METHOD

Title:

SUPPORTED NON-METALLOCENE CATALYST AND ITS PREPARATION METHOD

Document Type and Number:

WIPO Patent Application WO/2009/052700

Kind Code:

A1

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.
