ABSTRACT:
Thickening agents for aqueous systems are prepared by reacting aliphatic alcohols containing 8 to 22 carbon atoms with an ethylene oxide/propylene oxide mixture, then reacting the resulting polyether with 5 to 20 moles of ethylene oxide, and reacting the resulting alkoxylation product with a diepoxide, with 0.5 to 3 moles of alkoxylation product being used in the combination reaction per mole of diepoxide. The thickening agents may be blended with low molecular weight alcohol ethoxylates, and are especially suitable for hydraulic fluids.
