  • Synthetic lubricant composition and process
    Patent number: 7592411
    Abstract: A liquid polymer suitable for use as a lubricant base oil is produced by polymerizing ethylene and at least one alpha-olefin using a metallocene catalyst to provide a polymer which is then isomerized and hydrogenated to produce the liquid polymer.
