Abstract
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.
