  • Supported nonmetallocene catalyst, preparation and use thereof
    Patent number: 8981023
    Abstract: 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.
    Type: Grant
    Filed: October 13, 2010
    Date of Patent: March 17, 2015
    Assignees: China Petroleum & Chemical Corp., Sinopec Yangzi Petrochemical Co. Ltd.
    Inventors: Hongping Ren, Chuanfeng Li, Xiaoli Yao, Feng Guo, Zhonglin Ma, Haibin Chen, Kaixiu Wang, Jingwei Liu, Yaming Wang
