Abstract
Copolymers of alpha-olefins are generally disclosed, including methods of making such copolymers. In some embodiments, copolymers of alpha-olefins and certain unsaturated ester compounds are also disclosed, including methods of making such copolymers. Lubricant compositions including copolymers of alpha-olefins are also disclosed, as well as methods of using such compositions in certain lubricant applications.
Claims28
A composition, comprising:
- a copolymer comprising constitutional units formed from two or more monomers, the two or more monomers comprising
- a first monomer, which is an alpha-olefin having 8 to 18 carbon atoms, and
- a second monomer, which is an ester-alkene molecule, such as α-ester-alk-ω-ene molecule;
- where the composition has a kinematic viscosity at 100° C. of 25 to 200 centistokes.
