Abstract

The present invention relates to electroviscous liquids, essentially containing A) a linear and/or branched, optionally functionalised polyether or monomers thereof, the reaction product of such a polyether or of the monomers with monofunctional or oligofunctional compounds and optionally also further additives, B) dispersants and C) a non-aqueous dispersion medium. s
