    Abstract: An electrorheological fluid is prepared from a hydrophobic liquid medium and a dispersed particulate phase of (i) a polar solid material which is capable of exhibiting electrorheological activity in the presence of a low molecular weight polar material and (ii) a non-cellulosic polymeric material having a solubility parameter of about 15 to about 50 (MPa) and exhibiting substantially no electrorheological activity in the absence of a low molecular weight polar material. The fluid optionally contains a low molecular weight polar activator. The fluid has good electrorheological performance over a broad temperature range.
