Patent ID: 8877695

Claim:
A lubricant composition comprising: at least one estolide compound; and at least one compound selected from compounds of Formula II: wherein Y 1 is an unsubstituted C 5 to C 10 alkyl that is saturated and unbranched; Y 2 , Y 3 , and Y 4 , independently for each occurrence, are selected from unsubstituted C 4 to C 10 alkylene that is saturated and unbranched; U 1 and U 2 , independently for each occurrence, are selected from hydrogen and —C(═O)OR 10 ; R 9 and R 10 , independently for each occurrence, are selected from optionally substituted alkyl that is saturated and branched or unbranched; and R 5 and R 6 are hydrogen, or R 5 and R 6 , taken together with the carbons to which they are attached, form an optionally substituted cycloalkyl, wherein the dashed line represents a single bond, and wherein at least one of U 1 or U 2 is —C(═O)OR 10 , and wherein the composition exhibits a kinematic viscosity that is greater than the kinematic viscosity of the at least one estolide compound, and wherein the composition exhibits a pour point that is lower than the pour point of the at least one estolide compound.
