ABSTRACT:
A new class of lubricants based on the general features of archaebacterial lipids but not limited to lipids solely extracted from archaebacteria is described. These lubricant/additive molecules have the following features: bipolarity, ether bonds and branched biphytanyl chains. They can be double chained or single chained. This new class has the potential to be highly thermally and chemically stable due to the above mentioned features.
