Investigating the electron donor effect in the Ziegler-Natta catalyst used inpolyethylene gas phase processes

In this research, the effect of different electron donors (DIBP, THF, DEM, DES, and DEE) on theZiegler-Natta catalyst supported on the MgCl۲. ۰.۷ EtOH and the polyethylene obtained from it havebeen investigated through the kinetic graph, elemental analysis, activity, the size of the catalyst andpolymer, bulk density, and MFI of the polymer. Based on the obtained results, for the polymerizationof ethylene in the gas phase process, it is better to use a catalyst containing THF as an electron donorthat can obtain the catalytic properties required for that system.
