Abstract: This invention relates to water based functional fluids and antiwear compositions for such functional fluids. The functional fluids can be used in hydraulic systems or as metal working compositions to cool and lubricate surfaces which are in frictional contact during operations such as the turning, cutting, peeling, or grinding of metals. More specifically, the invention relates to a novel antiwear composition for inclusion in functional fluids which comprises:(a) a metal dialkyldithiophosphate, and(b) certain primary amines.It has been found that this combination of certain primary amines with the metal dialkyldithiophosphate provides improved wear properties over the use of the metal dialkyldithiophosphate alone, particularly at higher operating pressures such as 2000 psig and above. The functional fluid would also contain(c) a thickener and optionally(d) a carboxylic compound; and(e) a surfactant.

Abstract: This invention relates to synthetic polyether thickeners and thickened aqueous systems containing them. The thickeners are unique because they can be used in aqueous systems at less than ten percent weight concentration which will flow in a Vickers 104(C) Vane pump at use temperatures. These properties make them particularly useful for thickening hydraulic fluids used in high pressure vane and gear pumps. The thickeners are prepared by reacting conventional polyether polyols with alpha-olefin epoxides having an average of 6 to 12 total carbon atoms to obtain products with specific epoxide-to-hydroxyl ratios.

Abstract: The invention relates to a water-based functional fluid thickened by an associative polyether thickener whose thickening ability is enhanced by the addition of certain fatty acid amides.

Abstract: The invention relates to a water-based functional fluid thickened by an associative polyether thickener whose thickening ability is enhanced by the addition of certain quaternary ammonium salts.

Abstract: Improved hydraulic fluids or metalworking lubricants, utilizing mixtures of water, metal lubricants, metal corrosion inhibitors, and an associative polyether thickener, have reduced dependence of the viscosity on temperature achieved by the incorporation therein of an ethoxylated polyether surfactant.

Abstract: Permanent antistatic properties are imparted to melt-formed polymers by the incorporation therewith of a polymer composition prepared by reacting a hydrogen-reactive compound with an alkylene oxide adduct of a nitrogen-containing compound. Further, the polymer composition may be capped to minimize reaction with the melt-formed polymer.
