During the second year systematic measurements were performed on sterically stabilised suspensions of extreme particle sizes and covering a wide concentration range. A scaling law was found to hold up to moderate concentrations. The dependence of one of the scaling parameters on particle size was established. The scaling law was tested for 3 temperatures and two suspending fluids. Deviations from hard sphere behaviour were found, which are This effect was characterized by means of oscillatory measurements. attributed to stabiliser layer deformability. Under some conditions anomalous behaviour was encountered. For weakly flocculated systems time-dependent behaviour (i.e. thixotropy) was investigated. From experiments involving stepwise changes in shear rate some conclusions about the kinetics were obtained. The kinetics of recovery small amplitude oscillatory measurements. in effect of the after cessation of flow were investigated using preceding shear rate was found and information about the nature of the developing structure could be derived.
