    • 2] according to a modified PFT methodology. Polymerization conditions: MAO as cocatalyst, heptane as solvent, Al/MWNT = 2, AVZr = 2000, N/E = 2, T = 30 °C MAO was kept in contact with MWNTs for 10 h, then sonicated for 30 min at room temperature, and vacuum dried for 2 h at 200 °C After the addition of heptane, norbornene, ethylene, and metallocene were added. The copolymer MWNTs mixture was precipitated in MeOH/HCl.
