The method for producing polyolefin nanocomposites uses an aluminum nitride (AlN) nano-filler as a promoter of olefin polymerization with a metallocene catalyst. The method of making the polyolefin nanocomposites begins by combining a metallocene catalyst, such as a zirconocene catalyst, with aluminum nitride in a reactor. The reactor is then charged with toluene and methylaluminoxane, methylaluminoxane acting as a co-catalyst. The reactor is then heated at a constant temperature, and ethylene is added to the reactor to initiate polymerization of a polyethylene nanocomposite. Polymerization is then quenched by the addition of acidic methanol to the reactor, and un-reacted monomer is vented from the reactor. The resultant polyethylene nanocomposite is then washed in methanol and dried. The aluminum nitride nano-filler promotes the conversion of the olefin monomer to the polyolefin. |
