Abstract
Electrorheological systems of improved temperature range are obtained by including within the system a solid polymer insoluble in a low molecular weight activating material and in the hydrophobic medium of the fluid. The polymer contains hydrophilic functionality, and in the polymer a portion of the low molecular weight polar activating material is sorbed in an amount which reversibly increases with increasing temperature.
