摘要

Provided herein are compositions comprising at least one estolide compound of formula:;
in which n is an integer equal to or greater than 0; m is an integer equal to or greater than 1; R1, independently for each occurrence, is selected from optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched; R2 is selected from hydrogen and optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched; and R3 and R4, independently for each occurrence, are selected from optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched. Also provided are uses of the compositions described herein.

1. A method comprising:
transferring power in hydraulic machinery through the use of a power transfer medium, wherein the power transfer medium comprises an extreme pressure agent and an estolide base oil consisting essentially of at least one estolide compound, and said medium exhibits an EN selected from an integer or fraction of an integer that is equal to or less than 2, wherein EN represents the average number of estolide linkages for estolide compounds contained in the medium, and wherein the estolide base oil exhibits a kinematic viscosity of less than 45 cSt when measured at 40° C.
