Full TextAbstract
In order to investigate ethylene monomer pressure on fragmentation and in the morphology of the BCE Ziegler-Nata catalyst particles (TiCl4/MgCl2) in the early stages of polymerization reaction, polymerization was carried out at a 3.0 to 4.5 bar of the ethylene monomer pressure. Scanning electron microscope (SEM) has been used to investigate the effect of ethylene monomer pressure on morphology of the catalyst particles. SEM images show that with increasing pressure size of pores and cracks of the catalyst increases. Meanwhile activity of the catalyst was linearly increased from 16.0 to 18.6 (g PE. mmolTi-1. h-1) with increasing of the monomer pressure.
