<p>A double ester composition prepared by a three-step process comprising the non- ordered steps of a homopolymerization, a transesterification, and a capping, wherein the ordered steps include a sequence of homopolymerization, capping, and transesterification, or a sequence of transesterification, homopolymerization, and capping. The ester is useful particularly as a biolubricant having a high level of renewable carbons, and may exhibit particularly desirable properties relating to pour point, thermo-oxidative stability, and viscometric behavior due to reduced or eliminated levels of unsaturation in the final double esters.</p> |
