Polymerization of ethylene using a mixed pyridilimine [N,N] catalysts based on Ni & Fe

The pyridilimine catalysts based on nickel and iron were synthesized and were optimized for polymerization of ethylene, separately. A mixture of the catalysts at three different Ni:Fe weight ratios 50:50, 70:30 and 30:70 were used for the polymerization which carried out at [Al]/[Ni]+[Fe]=1200 molar ratio at 0°C for 2 hours. The highest activity obtained at 30:70 (Ni: Fe) where the percentage of the Fe catalyst in the mixture was higher
