    摘要: An automatic transmission oil composition includes 80 to 85 wt % of a base oil, 1 to 5 wt % of metallocene polyalphaolefin, 1 to 5 wt % of a detergent-dispersant, 0.01 to 0.03 wt % of a trinuclear molybdenum-based dialkyldithiocarbamate friction modifier, 3 to 10 wt % of a viscosity modifier, and 3 to 5 wt % of an anti-wear additive. The automatic transmission oil composition is prepared by mixing base oil with metallocene polyalphaolefin and a trinuclear molybdenum-based dialkyldithiocarbamate friction modifier at specific mixing ratios, whereby the dynamic friction coefficient can be maintained at an equivalent level and the metal friction coefficient can be reduced, thus improving the power transfer efficiency between transmission metals and fuel economy (an improvement of 1.5% or more), increasing durability, and minimizing energy loss.

    摘要: The present disclosure is directed to polymer compositions that can be useful as viscosity modifiers, comprising (a) a first ethylene-α-olefin copolymer having an ethylene content of from about 60 to about 80 wt % and (b) a second ethylene-α-olefin copolymer having an ethylene content of from about 40 to about 60 wt %. The polymer composition comprises about 35 wt % to about 50 wt of the first ethylene-α-olefin copolymer and about 50 wt % to about 65 wt % of the second ethylene-α-olefin copolymer. The polymer compositions are made by comprising producing a first ethylene-α-olefin copolymer in a first reactor, directing the first copolymer to a second reactor, producing the second ethylene-α-olefin copolymer in the second reactor and forming the polymer composition.

    摘要: A composition including polyalphaolefins that function as drag reducing agents and a process for the preparation of polyalphaolefins that function as drag reducing agents are disclosed. The process includes contacting alpha olefin monomers with a catalyst system, which includes a catalyst and an activator (co-catalyst) in a reactant mixture. The catalyst is a transition metal catalyst, preferably titanium trichloride, and the co-catalyst may include an alkylaluminoxane, alone or in combination, with a dialkylaluminum halide or a halohydrocarbon. The polymerization of the alpha olefin monomers produces a non-crystalline, ultra-high molecular weight polyalphaolefin having an inherent viscosity of at least 10 dL/g. The addition of the alkylaluminoxane during the polymerization process provides for a non-crystalline, ultra-high molecular weight polyalphaolefin and a more uniform molecular weight distribution of the resulting polyalphaolefin, thereby creating a drag reducing agent superior to known drag reducing agents. A process for forming a drag reducing agent comprising a non-crystalline, ultra-high molecular weight polyalphaolefin having an inherent viscosity of about at least 10 dL/g and a process for reducing drag in a conduit are also disclosed.

    摘要: A composition including polyalphaolefins that function as drag reducing agents and a process for the preparation of polyalphaolefins that function as drag reducing agents are disclosed. The process includes contacting alphaolefin monomers with catalyst particles in a polymerization mixture that includes a hydrocarbon solvent. The polymerization of the alphaolefin monomers produces polyalphaolefin drag reducing agents having an inherent viscosity of at least 10 dL/g. During polymerization of the polyalphaolcfin monomers, localized micelles compromising high molecular weight polyalphaolefin polymer are formed in micellar zones around the catalyst particles. The polymerization is conducted in the presence of a viscosity reducing agent that includes a substantially hydrophobic dispersant. The viscosity reducing agent is present in an amount sufficient to reduce the viscosity of the reaction mixture and disperse the localized micelles. The addition of the dispersant during the polymerization process provides for high molecular weight polyalphaolefin and a more uniform molecular weight distribution of the resulting polyalphaolefin. A process of forming a polyalphaolefin drag reducing agent in one or more polymerization reactors and a process for reducing drag in a conduit are also disclosed.
