| titleOfInvention | Catalyst composition for olefin polymerization and olefin polymerization method |
| abstract | The invention relates to the field of olefin polymerization catalysts, and provides a catalyst composition for olefin polymerization and an olefin polymerization method, wherein the catalyst composition comprises: (1) a first olefin polymerization catalyst (A) selected from the group consisting of metal complexes of the formula I, R 1 ～R 5 ，R 7 ～R 11 The same or different, each independently selected from hydrogen, hydrocarbyl or halogen; m is a group IVA metal, X, which may be the same or different, is selected from the group consisting of halogen, hydrocarbyl, hydrocarbyloxy; l is a group VIA element; (2) a second olefin polymerization catalyst (B) selected from the group consisting of metal complexes of the formula II, R 1 ‑R 10 The same or different, each is independently selected from hydrogen, hydrocarbyl, hydrocarbyloxy or halogen; r 21 、R 22 The same or different, each is independently selected from hydrogen, hydrocarbyl, hydrocarbyloxy or halogen; m is a group VIII metal, and X is selected from halogens; (3) a chain shuttling agent; (4) a cocatalyst. The catalyst composition still has high activity at high temperature. |
