    Abstract: The present invention is directed towards a lubricating oil comprising a random copolymer of an &agr;-olefin/aromatic vinyl compound, wherein the copolymer has a viscosity falling within a specific range and comprises ethylene, an aromatic vinyl compound, and optionally an &agr;-olefin. The lubricating oil possesses excellent viscosity properties, thermal stability, oxidation stability, abrasion resistance, and compatibility with lubricating oil additives. The random copolymer having a different viscosity range is useful as a viscosity index improver and a compatibilizing agent for a lubricating oil. The invention also provides a lubricating oil composition comprising a base oil and the viscosity index improver or the compatibilizing agent. The invention further provides a fuel oil composition comprising a fuel oil fluidity improver based on the above random copolymer having a different viscosity range and a middle fraction fuel oil having a boiling point of 150 to 400° C. The fuel oil composition prevents an increase in viscosity of the middle fraction fuel oil, lowers the clogging point and the flow point in a low-temperature filter, and inhibits the abrasion of a fuel jet nozzle.

    Abstract: 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.
