| titleOfInvention | Olefin multistage polymerization method |
| abstract | (57) [Summary] [PROBLEMS] To be excellent in processing characteristics, especially in hollow molding, such as drawdown resistance and uniform stretchability, and also excellent in mechanical strength such as impact resistance and ESCR (environmental stress cracking resistance). To provide a method for multi-stage polymerization of olefins, from which olefin polymers are obtained. SOLUTION: A multi-stage polymerization method for olefins, comprising at least the following two polymerization steps. (Polymerization Step I) [A] From the group consisting of cations containing at least one atom selected from the group consisting of transition metal atoms of Groups 4B to 6B of the Periodic Table and anions of halogen atoms, inorganic acids and organic acids. A polymerization step I for polymerizing an olefin in the presence of a solid catalyst component comprising a salt comprising at least one selected anion supported on a carrier [B] and, if necessary, a catalyst comprising an organoaluminum compound [C]. . (Polymerization Step II) In the polymerization step I, the obtained olefin polymerization product is further added without substantially deactivating the catalyst. Periodic table 4B having at least one conjugated five-membered ring ligand A polymerization step II in which a transition metal compound [D] of a Group 6B to 6B is added to polymerize an olefin; |
