Disclosed is a supported nonmetallocene catalyst and preparation thereof. The supported nonmetallocene catalyst is characterized by a high catalyst activity for olefin polymerization and a significant monomer effect. Further disclosed is use of the supported nonmetallocene catalyst in olefin homopolymerization/copolymerization. The polymer produced therewith is characterized by superior particle morphology, a high bulk density, and/or a narrow molecular weight distribution.

Supported nonmetallocene catalysts, preparation and use thereof

This invention relates to a mesoporous carbon supported copper based catalyst comprising mesoporous carbon, a copper component and an auxiliary element supported on said mesoporous carbon, production and use thereof. The catalyst is cheap in cost, friendly to the environment, and satisfactory in high temperature resistance to sintering, with a highly improved and a relatively stable catalytic activity.

Mesoporous carbon supported copper based catalyst, production and use thereof

The present invention relates to a magnesium compound-supported nonmetallocene catalyst, which is produced by directly contacting a catalytically active metallic compound with a nonmetallocene ligand-containing magnesium compound, or by directly contacting a nonmetallocene ligand with a catalytically active metal-containing magnesium compound, through an in-situ supporting process. The process is simple and flexible. In the process, there are many variables in response for adjusting the polymerization activity of the catalyst, and the margin for adjusting the catalyst load or the catalyst polymerization activity is broad. The magnesium compound-supported nonmetallocene catalyst according to this invention can be used for olefin homopolymerization/copolymerization, in combination with a comparatively less amount of the co-catalyst, to achieve a comparatively high polymerization activity. Further, the polymer product obtained therewith boasts high bulk density and adjustable molecular weight distribution.

This invention relates to a supported nonmetallocene catalyst for olefin polymerization, which is produced by directly reacting a nonmetallocene ligand with a catalytically active metallic compound on a carrier through an in-situ supporting process. The process according to this invention is simple and feasible, and it is easy to adjust the load of the nonmetallocene ligand on the porous carrier. The supported nonmetallocene catalyst according to this invention can be used for olefin homopolymerization/copolymerization, even in combination with a comparatively less amount of the co-catalyst, to achieve a comparatively high polymerization activity. Further, the polymer product obtained therewith boasts desirable polymer morphology and a high bulk density.
