Method of making polyolefin with a silicon nitride nano-filler |
摘要 |
The method of making polyolefin with a silicon nitride nano-filler uses silicon nitride (SiN) as a promoter for in situ polymerization with a zirconocene catalyst. The method includes adding the bis(cyclopentadienyl) zirconium dichloride catalyst and nanoparticles of silicon nitride to a reactor. The reactor is then charged with toluene and a methylaluminoxane co-catalyst, and is heated for a period of time sufficient to bring the reactor to a polymerization reaction temperature. Nitrogen gas is removed from the reactor following the heating, and then ethylene monomer is fed into the reactor, initiating polymerization. The polymerization is then quenched, and non-reacted monomer is vented. The polyolefin product is then removed from the reactor, washed and dried. |
