Abstract

See full text

This invention relates to a polyalpha-olefin (and hydrogenated analogs thereof) comprising more than 50 mole % of one or more C5 to C24 alpha-olefin monomers where the polyalpha-olefin has: a) 40 mole % or more of mm triads, b) a Bromine number of Y or greater, where Y is equal to 89.92*(V)′°5863, where V is the Kinematic Viscosity of the polyalpha-olefin measured at 100° C. in cSt, and c) 1,2 disubstituted olefins present at 7 mole % or more, preferably having Z mole % or more of units represented by the formula: where j, k and m are each, independently, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, or 22, n is an integer from 1 to 350, and where Z=8.420*Log(V)−4.048, where V is the kinematic viscosity of the polyalpha-olefin measured at 1000 C in cSt This invention also relates to process to produce such polyalpha-olefins.
