摘要：
The invention relates to the use of combinations of water-soluble polymeric polyether polyols, in which at least 50% of the terminal hydroxyl groups are blocked by reaction with a monoisocyanate incorporating a long-chain aliphatic hydrocarbon radical, and certain surfactants as thickener systems for high water based functional fluids and to the thickened high water based functional fluids.
