The iron-based catalyst could oligomerize ethylene to α-olefins and they copolymerized with ethylene the same time to form PE/MMT nanocomposites in the interlayer of MMT under rac-Et(Ind)2ZrCl2. The catalytic system was of high polymeric activities towards ethylene copolymerization and produced branched PE matrix. Characterization of the resultant PE/MMT nanocomposites was performed with 13C nuclear magnetic resonance (NMR), X-ray diffraction (XRD), transmission electron microscopy (TEM), differential scanning calorimeter (DSC), and thermogravimetric analysis (TGA) etc. Also investigated were the mechanical properties of the resulting PE/MMT nanocomposites.
