MULTIFUNCTIONAL SYNTHETIC LUBRICANT BASESTOCKS

摘要

The invention describes synthetic lubricant basestocks containing an ester function combined with a carbamate function and/or an amide function. These multifunctional ester fluids may be prepared via condensation of alkanolamines and/or alkylamines with cyclic carbonates and/or lactones followed by reaction with carboxylic acids. Higher viscosity complex multifunctional esters are obtained with polycarboxylic acids or anhydrides and/or polyamines.
