  • Lubricant Compositions Including Alpha-Olefin Copolymers
    Publication number: 20160108335
    Abstract: A lubricant composition may include a copolymer having constitutional units formed from monomers including an alpha-olefin and an ?-ester-alk-?-ene molecule, where the composition has a kinematic viscosity at 100° C. of at most 20 centistokes, or of at least 40 centistokes. A lubricant composition may include a copolymer having constitutional units formed from monomers including an alpha-olefin, an ?-ester-alk-?-ene molecule and an ?-(carboxylic acid)-alk-?-ene molecule, where the composition has a viscosity that varies as the molar ratio of the ?-ester-alk-?-ene molecule ?-(carboxylic acid)-alk-?-ene molecule in the monomers varies.
