| titleOfInvention | Naphthalene nucleus containing alpha-diketiminato nickel (II) composition as well as preparation method and application thereof |
| abstract | The invention discloses a naphthalene nucleus containing alpha-diketiminato nickel (II) composition catalysts for olefin polymerization. By changing the steric hindrance of a ligand framework structure and increasing the steric hindrance of imide ortho-space, a benzene ring is introduced to the ortho-position of the benzene ring of the imide to form a naphthalene nucleus with stronger rigidity, thereby stabilizing the active centre. The composite catalyst prepared from the composition and diethylaluminum chloride as a cocatalyst can catalyze vinyl to polymerize with higher activity under higher temperature and catalyze vinyl to polymerize under lower aluminum-nickel molar ratio to obtain polyethylene with high molecular weight. |
