Synthesis, characterization, and ethylene polymerization of 1-[2,4-bis(bis(4-fluorophenyl)methyl)naphthylimino]-2-aryliminoacenaphthylnickel bromides: influences of polymerization parameters on polyethylenes

The nickel bromides ( C1–C5 ), upon activation with Et 2 AlCl, exhibited high activities toward ethylene polymerization obtaining polyethylenes with M w from 0.86–5.58 × 10 5 g mol −1 and narrower PDI (1.22–1.99).
