Supported nonmetallocene catalyst, preparation and use thereof
This invention relates to a supported nonmetallocene catalyst and preparation thereof. The supported nonmetallocene catalyst can be produced with a simple and feasible process and is characterized by an easily controllable polymerization activity. This invention further relates to use of the supported nonmetallocene catalyst in olefin homopolymerization/copolymerization, which is characterized by a lowered assumption of the co-catalyst as compared with the prior art.
