  • Polyamide and functional fluid containing same
    Patent number: 4374741
    Abstract: 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.
    Type: Grant
    Filed: July 21, 1981
    Date of Patent: February 22, 1983
