Abstract
Provided are an α-olefin copolymer useful as a high-viscosity lubricant oil excellent in viscosity characteristics, low-temperature characteristics and oxidation stability, and a lubricant oil containing the copolymer. The α-olefin copolymer is a 1-decene/1-dodecene copolymer produced by the use of a doubly bridged metallocene catalyst.
Claims9
