关键词	A series of late-transition metal complexes supported with chlorinated bis(arylimino)pyridine ligands [2 Ar = 2 Ar = 2 Ar = 2 Ar = 4-Cl-2 Ar = 4-Br-2 6-(ArN=CCl)(2)C5H3N]MtCl(2) (Ar = 2 6-(Pr2C6H3)-Pr-i 6-Et2C6H3 6-Me2C6H3 6-Me2C6H2 6-Me2C6H2 4 Mt = Fe (1b) Mt = Co (1c) Mt = Fe (1d) Mt = Fe (1e) Mt = Fe (1f) 6-Me3C6H2 Co (2b) Ni (3c) Co (2d) Co (2e) Co (2f)) were synthesized. At the presence of methylaluminoxane (MAO) Mt = Fe (1a) Fe(II)- and Co(II)- based complexes were highly active towards ethylene polymerization Co (2a) affording polymers with bimodal and unimodal molar. mass distributions Ni (3a) respectively while the Ni(II)-based complexes gave no polymer products. Moreover the obtained polyethylenes were predominately saturated and vinyl-terminated for Fe(II)- and Co(II)-based complexes respectively. Changing the ligand environment polymerization parameters also posed a great influence on the catalytic activities and the properties of the resulting polymers. (C) 2014 Elsevier Ltd.
