Abstract:
1. A hydroxyaromatic functionalized polyalpha-olefin comprising the product of the combination of: a) a polyalpha-olefin having 0 wt % isobutylene and comprising one or more C3 to C20 linear alpha-olefins selected from the group consisting of 1-decene, 1-undecene, 1-dodecene, 1-tridecene and 1-tetradecene, and having at least 10% vinylidene unsaturation, a viscosity index of 80 to 400, an Mn of 300 to about 20,000, and a pour point of 0° C. or less; and b) a hydroxyaromatic moiety; wherein the aniline point of the functionalized polyalpha-olefin is at least 10° C. lower than the aniline point of the polyalpha-olefin, and wherein the oxidation induction temperature is 225° C. or more; and wherein the functionalized polyalpha-olefin has more than 20% of the benzylic carbon atoms present as quaternary carbon atoms.
