    Abstract: Water-soluble salts (e.g., alkali metal, ammonium or watersoluble amine salts) of styrene-maleic anhydride copolymer halfesters are employed in aqueous solutions as coolants and lubricants for metal-working operations e.g., metal cutting and abrading. The copolymers are esterified with both a fatty alcohol having from 10 to 22 carbon atoms and a lower alkoxy polyethylene glycol. Metal-working lubricant compositions are also formulated which comprise these salts along with extreme pressure agents such as amine salts of fatty acids and organic phosphate esters. Other additives may also be employed in the lubricating compositions of this invention.

    Abstract: Unsaturated cyclic keto acid may be prepared by cyclizing alken-2-yl dicarboxylic acid anhydride with Lewis acid catalyst in anhydrous Friedel-Craft solvent. Amides of these unsaturated cyclic keto acids useful as friction improvers in lubricating oils, may be prepared by reaction of an amine such as ethanolamine with an unsaturated cyclic keto acid.
