Abstract: A catalyst consisting essentially of at least one tertiary monophenyl amine having a formula R1R2N-aryl, where R1 and R2 are the same or different, and each is a hydrogen, an alkyl, or a cycloalkyl group, where at least one of R1 and R2 contain at least one carbon atom; at least one titanium halide having a formula TiXm, where m is from 2.5 to 4.0 and X is a halogen containing moiety; and at least one cocatalyst having a formula AlRn Y3-n where R is a hydrocarbon radical, Y is a halogen or hydrogen, and n is 1-3. Further, the catalyst is absent of a carrier or support.

Abstract: A method of reducing drag in a conduit. The method includes producing ultra high molecular weight (UHMW) C4-C30 ?-olefin drag reducing agent (DRA) and introducing the UHMW C4-C30 ?-olefin polymer DRA into the conduit to reduce drag in the conduit. The catalyst consists essentially of at least one tertiary monophenyl amine selected from the group consisting of N,N-diethylaniline, N-ethyl-N-methylparatolylamine, N,N-dipropylaniline, N,N-diethylmesitylamine, and combinations thereof; at least one titanium halide having a formula TiXm, where m is from 2.5 to 4.0 and X is a halogen containing moiety; and at least one cocatalyst having a formula AlRnY3-n where R is a hydrocarbon radical, Y is a halogen or hydrogen, and n is 1-20. Further, the catalyst is absent of a carrier or support.

Abstract: A method of producing ultra high molecular weight (UHMW) C4-C30 ?-olefin drag reducing agent (DRA). The method includes polymerizing in a reactor a first ?-olefin monomer in the presence of catalyst and hydrocarbon solvent to produce the DRA.

Abstract: The supported metallocene catalyst for olefin polymerization is (nBuCp)2ZrCl2 impregnated onto a silica support having MAO tethered thereon. The catalyst is made by dehydroxylating silica, adding MAO dropwise to a slurry of the silica in toluene, heating the mixture for several hours, reacting (nBuCp)2ZrCl2 in toluene solvent with the MAO/silica support, and drying the catalyst under vacuum. The catalyst may be used, e.g., to catalyze copolymerization of ethylene with 1-hexene.

Abstract: The supported metallocene catalyst for olefin polymerization is (nBuCp)2ZrCl2 impregnated onto a silica support having nBuSnCl3 and MAO tethered thereon. The catalyst is made by dehydroxylating silica, forming a silica/toluene slurry, injecting nBuSnCl3 into the slurry, refluxing the silica/toluene/nBuSnCl3 slurry, adding MAO dropwise to a slurry of the nBuSnCl3-functionalized silica in toluene, heating the mixture for several hours, reacting (nBuCp)2ZrCl2 in toluene solvent with the MAO/nBuSnCl3-functionalized silica support, and drying the catalyst under vacuum. The catalyst may be used, e.g., to catalyze copolymerization of ethylene with 1-hexene.
