Abstract:
This disclosure relates to a liquid syndiotactic polyalphaolefin, sPAO, comprising one or more C4 to C24 monomers, said sPAO having: a) an rr triad content of 5 to 50% as measured by 13C NMR; b) an mr triad content of 25 to 60% as measured by 13C 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 13C NMR) of less than 9; f) a ratio of vinylidene to 1,2-disubstituted olefins (as determined by 1H 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).
