POLYAMIDE DERIVATIVE OF A POLYOXYALKYLENE DIAMINE, AQUEOUS FUNCTIONAL LIQUID CONTAINING A POLYAMIDE DERIVATIVE, AND METHOD FOR PROCESSING METALS IN THE PRESENCE OF A WATERY FUNCTIONAL LIQUID.

摘要

Polyoxyalkylene polyamide lubricants having a terminal carboxylic acid group and a terminal amine group in the same molecule and a degree of polymerization of from 2 to 10 and salts thereof are provided. Stable aqueous based compositions are prepared from the polyamide or its salt, that are useful metal working and hydraulic fluids.
