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.
