Large sterically hindered flexible diimine ligands, nickel and palladium diimine complexes based thereon and their catalytic applications |
| abstract |
The invention discloses large sterically hindered flexible diimine ligands, diimine nickel and palladium complexes based thereon and their catalytic applications. By introducing flexible substituents of different structures on the diimine ligands, a series of The steric effect of nickel diimide and palladium catalysts. The catalyst obtained by the invention has high thermal stability and high activity for catalyzing olefin polymerization, and the catalyst can control the molecular weight and branching density of polyolefin by changing the chain length of the substituent. |
