| titleOfInvention | Ziegler-Natta olefin polymerization catalysts with single-site center property |
| abstract | The invention relates to novel Ziegler-Natta olefin polymerization catalysts with single-site center property. The catalysts are characterized in that the catalysts are obtained by adopting a one-pot method and adding novel multidentate ligands (I), magnesium compounds, metal compounds and carriers to tetrahydrofuran solution for treatment. Under the action of alkylaluminium or alkylaluminoxane and other cocatalysts, the catalysts can obtain ethylene copolymer and homopolymer products with controllable molecular weight distribution (1.6-40) and uniformly distributed comonomers through high activity. The catalysts can realize catalytic ethylene polymerization, as well as the slurry-process or gas-phase-process homopolymerization or copolymerization of ethylene and 1-olefin, annular olefin, polar monomer and the like. |
