Investigating the effect of Spherical and Cylindrical MCM-41 as Support in MCM-41/TiCl4/Mgcl2/THFCatalyst on Polyethylene Morphologies

MCM-41 is one of the mesoporous materials that can be synthesized in different shapes including cylindrical (Cy) and spherical (Sp) [1].Due to their high specific surface areas(SSA) they are widely used for supporting different types of catalysts. These types of silicious materials when are used asthe support for Metallocene or Ziegler-Natta catalysts in ethylene polymerization can act as a nano-extruder and produce polyethylene (PE) nano-fibers [2, 3].In this work MCM-41s with Cy and Sp morphologies are synthesized and the effect of their differentstructure natures isinvestigated on the morphology andthermal behaviour of PEs.Their effects on the activity of the catalysts are also discussed
