We use dynamic light scattering to measure the time-dependent increase of the average hydrodynamic radius of colloidal silica particles in the presence of salt. This increase appears to be linear in time up to twice the radius of unaggregated particles. The method is a very useful tool in monitoring

The random phase approximation has been used to extend the Leibler theory for the stability limit of a homogeneous melt of A-B diblock copolymers to examine the onset of microphase and macrophase separation in a variety of ABC block copolymer systems. The stability limit is located by the divergence
## Abstract The effect of electrolytes (NaCl and CaCl~2~) and polymers (CPAM and HPAM) on the thixotropy of Mg‐Al‐layered double hydroxide (LDHs)/kaolinite dispersions has been investigated. It was observed that the type of thixotropy in LDH/kaolinite dispersions may be affected by NaCl, but not by
