Abstract
A method of making a polyolefin including, mixing a layered double hydroxide (LDH), and a zirconocene complex in a non-polar solvent to form a first mixture. The method further includes degassing the first mixture and adding an olefin to form a second mixture. The method further includes adding an aluminoxane cocatalyst to the second mixture and reacting for at least 10 minutes to form a reaction mixture including the polyolefin. The method further includes separating the polyolefin from the reaction mixture. The polyolefin has a melting temperature of 120-130° C. The zirconocene complex is supported on the LDH to form a supported catalyst complex in the first mixture.
