ABSTRACT:
Lubricants for machining, deformation of machining and cold rolling of metals. The lubricant comprises an aqueous solution of at least one of the copolymers of ethylene oxide and higher alkylene oxides having 3 to 8 carbon atoms, of the copolymers of an acrylic acid or methacrylic acid and an acrylic ester, or a polymer of polyvinylpyrrolidone and/or of polyvinyl alcohol. The lubricants are useful in any operation involving the working of metals like steel, copper and the like. They have remarkable load-bearing capacity, and are biodegradable.
