This disclosure relates to a liquid syndiotactic polyalphaolefϊn, sPAO, comprising one or more C 4 to C 24 monomers, said sPAO having: a) an rr triad content of 5 to 50 % as measured by 13 C NMR; b) an mr triad content of 25 to 60 % as measured by 13 C NMR, where the mr to mm triad ratio is at least 1.0; c) a pour point of Z °C or less, where Z = 0.0648X-51.2, where X = kinematic viscosity at 100 °C as reported in centistokes (cSt); d) a kinematic viscosity at 100 °C of 100 cSt or more (alternatively 200 cSt or more); e) a ratio of mr triads to rr triad (as determined by 13 C NMR) of less than 9; f) a ratio of vinylidene to 1,2-disubstituted olefins (as determined by 1 H NMR) of less than 8; g) a viscosity index of 120 or more; and h) an Mn of 40,000 or less. This disclosure further relates to processes to make and use sPAOs, including those having any combination of characterics a) to h). |
