| Abstract | A series of 8-(arylimino)-5,6,7-trihydroquinolines ligand pendant fluorenyl group at N-aryl ring, and their nickel complexes (Ni1 − Ni5) have been prepared and characterized. Once activated with Et2AlCl, the complexes Ni1, Ni2, and Ni3 bearing ligands from para-fluorenylaniline produced unimodal polyethylenes; on the contrary complexes Ni4 and Ni5 gave bimodal polyethylenes due to steric influence of ligands from ortho-fluorenyl anilines. With a increment of Et2Zn/Ni4 ratio from 0 to 400, the distinct bimodel polyethylenes were obtained with molecular weights shifted from 14.3 to 57.6 kg·mol−1; apart shiftment to higher molecular weights, the portion of low molecular weight decreased along with higher portion of high molecular weight. |
