  • Patent number: 8242219
    Abstract: 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.

  • Publication number: 20110040052
    Abstract: The invention relates to a process for forming a polyalphaolefin, the process comprising the step of polymerizing at least one C8-C12 monomer, preferably a decene such as 1-decene, in the presence of an aluminoxane, an activator and a metallocene to form the polyalphaolefin, wherein the molar ratio of the aluminoxane to the metallocene is less than 250:1. The invention also relates to a process for forming a polyalphaolefin having a desired kinematic viscosity from at least one monomer in the presence of an aluminoxane, an organoboron compound and a metallocene. The process comprises the steps of, inter alia, providing a correlation between (i) the molar ratio of the aluminoxane to at least one of the organoboron compound and the metallocene, and (ii) the kinematic viscosity of the polyalphaolefin to form polyalphaolefins having predictable viscosities.

  • Patent number: 7829646
    Abstract: The present invention is directed to PE-100 ethylene copolymers and pipe made thereof having a Tabor abrasion between about 0.01 and about 0.001 grams lost/1000 revolutions. These copolymers are formed by contacting ethylene with at least one mono-1-olefin comonomer having from 2 to about 10 carbon atoms per molecule in a reaction zone under polymerization conditions in the presence of a hydrocarbon diluent, a catalyst system, and a cocatalyst. Additionally, the comonomers may be selected from mono-1-olefins having 4 to 10 carbon atoms, such as, 1-hexene, 1-butene, 4-methyl-1-pentene, 1-octene, and 1-decene. Further, these ethylene copolymers may be employed to produce PE-100 pipe having both small diameters and diameters in excess of 42 inches substantially without sagging or other gravitational deformation. Copolymers of ethylene and 1-hexene are disclosed which are used to produce PE-100 pipe.
