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

Abstract

The nickel bromides (<bold>C1–C5</bold>), upon activation with Et₂AlCl, exhibited high activities toward ethylene polymerization obtaining polyethylenes with <italic>M</italic>_w from 0.86–5.58 × 10⁵ g mol⁻¹ and narrower PDI (1.22–1.99).
