AbstractAn unsymmetric 2,6-bis(imino)pyridine iron(II) complex 1' was synthesized. The relationship between catalyst structure and its activity in ethylene polymerization is discussed. The kinetic behavior of ethylene polymerization and the effects of polymerization conditions such as temperature, aluminum/iron molar ratio on the activity of catalyst and the characteristics of polyethylene were reported. The unsymmetric catalyst 1' has a good catalytic performance of 3.47 x 10(6) gPE . mol-1. Fe . h(-1) at 40degreesC with aluminum/iron molar ratio = 2500. A dependence of catalyst activity on the methylaluminoxane (MAO) concentration and reaction temperature was found. The molecular weight (MW) of polyethylene with broad dispersity is about 10(4)-10(5) g/mol. The melting temperature and branching of polyethylenes vary with changing reaction temperature and aluminum/iron molar ratio.
