Abstract
Abstract Carboxylic acid terminated diamides and alkali metal, ammonium or amine salts thereof are provided which are derived from the reaction of organic polycarboxylic acids and polyoxyalkylene diamines. The diamides have lubricating properties and are especially useful in aqueous metal working fluids.
