LUBRICANT COMPOSITIONS INCLUDING ALPHA-OLEFIN COPOLYMERS

摘要

A lubricant composition may include a copolymer having constitutional units formed from monomers including an alpha-olefin and an a-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 a-ester-alk-?-ene molecule and an cc- (carboxylic acid)-alk-?-ene molecule, where the composition has a viscosity that varies as the molar ratio of the a-ester-alk-?-ene molecule a-(carboxylic acid)-alk-?-ene molecule in the monomers varies.
