Effect of Pore Diameter of Nano-porous Rod-like MCM-41s in MCM-41/TiCl4/MgCl2/THF Catalytic System on the Morphology of As-Synthesized PEs

MCM-41 is one of the mesoporous materials that is widely used for supporting different types of catalysts. When it is used as the support for Metallocene or Ziegler-Natta catalystsin ethylene polymerization it acts as a nano-extruder and produces polyethylene (PE) nano-fibers [1]. In this workvarious MCM-41 with different pore diameters were synthesised and the effect of pore diameters was investigated on the morphology of the polyethylenes.
