Estolides are a class of unique bio-based oils with a variety of uses. Their oligomeric structure contains fatty acid repeat units, with secondary ester linkages on the alkyl backbone. In the general structure shown above, functional groups denoted as α and β, oligomer length n, and the fatty acid feedstock can all be manipulated in order to achieve desirable performance properties. Relevant technical performance properties include increasing or decreasing viscosity and polarity, as well as improving cold temperature properties and oxidative stability.
