Synthesis of PE/MWCNT Nanocomposites Through in-situ polymerization using Mixture of Pyridilimine [N, N] catalysts based on Ni & Fe

The pyridilimine catalysts based on nickel and iron were synthesized and the condition of ethylene polymerization was optimized, respectively. A mixed of the catalysts with three different weight ratios were used for the polymerization. Moreover, nanocomposite synthesis through in-situ polymerization was carried out with MWCNT at 50:50 weight ratio of catalysts. As a general result, the activity of catalysts decreased in presence of the MWCNT with 20-30 and 30-50nm diameters
