Effect of FeCl3 on the Performance of TiCl4/MgCl2(Etoxide type)/SiCl4/TEAL Catalytic System in Ethylene Polymerization

In this study, different catalyst support systems containing Mg(OEt)2, Mg(OEt)2/FeCl3, Mg(OEt)2/SiCl4 and Mg(OEt)2/FeCl3/SiCl4 were prepared and employed in TiCl4 based Ziegler-Natta catalyst synthesis followed by slurry phase ethylene polymerization. Results revealed that FeCl3/SiCl4 modified Mg(OEt)2 based catalyst system has better performance in terms of catalyst activity and polymer properties when compared with the catalyst systems in the presence of single FeCl3 or SiCl4 or it without any modifier
