  • Electroviscous liquid based on dispersed modified polyethers
    Patent number: 5496483
    Abstract: Disclosed are electroviscous liquid essentially containingA) A linear and/or branched, eventually functionalized, polyether or the monomers thereof, the conversion product of such polyether resp. such monomer with mono- or oligo functional compounds and eventually additional additives, andB) a dispersing agent, andC) a non-aqueous dispersion-medium.In an embodiment a cavity contains the electroviscous liquid and has parts movable with relation to each other and electrode means for generating an electrical field within the cavitywherein applying the electrical field increases the viscosity of the liquid.
