Abstract
This invention is directed to an electrorheological fluid which comprises nonconductive particulate susceptible to ionic and electronic polarization dispersed in a nonconductive fluid. The nonconductive particulate are a phenoxy organometallic salt. This salt is the reaction product of an esentially stoichiometric amount of phenoxy salt soluble or dispersible in a liquid and a divalent metal salt. The phenoxy salt can be made by reacting diphenol material with active metal or active metal hydroxide.
