Vinyl polymerization of norbornene by Ni(II) α-diimine complexes: Effect of type and position of alkyl aryl substituents |
| 초록 |
Norbornene is known to polymerize by cationic or radical, ring opening metathesis and also by vinylic addition methodologies resulting polymers of different microstructure. The 2,3-connected rotationally strongly constrained vinyl-type polynorbornene has recently in attraction because of their unique physical properties such as high Tg, optical transparency and low birefringence. The transition metal complexes such as metallocene and late-metal catalysts with their tunable ligand structure polymerize olefins with stereo electronic influence towards both activity and microstructure of the polymer. There has been lot of reports on influence Ni based catalyst with different substituent in α-olefin polymerization. In the present work we focused on effect of differently aryl substituted Ni(II) α-diimine complex towards the polymerization of a bulky olefin norbornene. The catalyst with no substituent around metal center showed highest activity in contrast to ethylene polymerization. |
