Use of special polyethers as base oils for lubricant oil formations

摘要

Lubricant oil formulations which are corrosive to a particularly small degree and are based on water-soluble polyethers are obtained if polyethers are used which were prepared by adding bases to mono- to tetrafunctional compounds containing active H atoms and addition of alkylene oxides, at least 40% by weight of the alkylene oxides being ethylene oxide, at 112 to 125 DEG C.
