The MCM-41 (Mobil Composition of Matter) and SBA-16 (Santa Barbara Amorphous) supported TiCl4 and TiCl4/MgCl2 catalysts with different molar ratios of Mg/Ti were synthesized and used for ethylene polymerization under atmospheric pressure. The nanochannels of these supports serve as a nanoscale polymerization reactor and the polyethylene nanofibers were extruded during the reaction. The effect of MgCl2 on catalytic activity and morphology of resulting polyethylene has been investigated too. MgCl2 has enhanced the catalytic activities and made the SBA-16/MgCl2/TiCl4 catalytic system has fibrous morphology.
