  • Supported nonmetallocene catalysts, preparation and use thereof
    Patent number: 9334339
    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.
    Type: Grant
    Filed: June 9, 2014
    Date of Patent: May 10, 2016
    Assignees: CHINA PETROLEUM & CHEMICAL CORPORATION, SINOPEC YANGZI PETROCHEMICAL COMPANY LTD.
    Inventors: Chuanfeng Li, Hongping Ren, Lin Kan, Feng Guo, Wenrui Wang, Yuming Yi, Shaohui Chen, Jiye Bai
