Method of making polyolefin nanocomposites
 
Al-Harthi et al of King Fahd University of Petroleum and Minerals, Saudi Arabia, produced polyolefin nanocomposites using 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. (RDC 9/3/2012)
