This invention relates to an aqueous gel comprising a specified capped polyether polymer and a surfactant. Preferred capped polyether polymers can be obtained by modifying a conventional polyether polyol with an alpha-olefin epoxide having an average of about 20 to 45 carbon atoms or mixtures thereof.

Polymers which form gels at low concentrations in water

The invention relates to thickened fuctional fluids. The functional fluids can be used in hydraulic systems or as metalworking compositions to cool and lubricate surfaces which are in frictional contact during operations such as the turning, cutting, peeling, or grinding of metals. The functional fluid contains a diluent, a dialkyldithiophosphate, a compound which is a source of molybdate ion, a polyether nonionic surfactant, and an associative polyether thickener.

Functional fluids containing associative polyether thickeners, certain

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.

Water-based functional fluids thickened by the interaction of an

The invention relates to functional fluid concentrates and functional fluids which can be prepared by mixing the concentrates with water. The functional fluids can be used in hydraulic systems or as metalworking compositions to cool and lubricate surfaces which are in frictional contact during operations such as the turning, cutting, peeling, or grinding of metals. The functional fluid concentrate comprises:

Functional fluids and concentrates containing associative polyether

The invention relates to functional fluid concentrates and functional fluids which can be prepared by mixing the concentrates with water. The functional fluid concentrate comprises certain basic zinc salts as cloud point raising additives; a polyether nonionic surfactant; and an associative polyether thickener.

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.
