Patent ID: 8450256

Claim:
A composition comprising two or more estolide compounds, said composition having: an EN selected from an integer or fraction of an integer that is equal to or greater than 4, wherein the EN is the average number of estolide linkages in compounds according to Formula I; a kinematic viscosity equal to or greater than 200 cSt when measured at 40° C.; and a pour point equal to or lower than −40° C., wherein said two or more estolide compounds are selected from compounds of Formula I: wherein x is, independently for each occurrence, an integer selected from 0 to 20; y is, independently for each occurrence, an integer selected from 0 to 20; n is an integer selected from 0 to 12; R 1 is an optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched; and R 2 is an optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched, wherein each fatty acid chain residue of said two or more estolide compounds is independently optionally substituted.
