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.

A method of making a polyolefin, comprising:
- mixing a layered double hydroxide (LDH), and a zirconocene complex in a nonpolar solvent to form a first mixture;
- degassing the first mixture and adding an olefin to form a second mixture;
- adding an aluminoxane cocatalyst to the second mixture and reacting for at least 10 minutes to form a reaction mixture comprising the polyolefin;
- and
- separating the polyolefin from the reaction mixture;
- wherein the polyolefin has a melting temperature of 120-130° C.,
- wherein the zirconocene complex is supported on the LDH to form a supported catalyst complex in the first mixture,
- wherein the LDH is a NiFe LDH, and
- wherein an intercalating anion of the LDH is a dodecyl sulfate (DDS) anion.
