AMINO-AMIDE LUBRICANTS DERIVED FROM POLYMERIC FATTY ACIDS AND POLY(OXYETHYLENE) DIAMINES

摘要

Amino-amides having a molecular weight between 500 and 1000 obtained by the reaction of polymeric fatty acids with poly(oxyethylene) diames are readily compatible with water in all proportions and form clear, aqueous solutions which exhibit rust preventive characteristics and have excellent lubricating properties. The aqueous lubricating solutions have superior extreme pressure properties and exhibit rust preventive properties not heretofore possible with water-soluble dimer-based lubricants.
