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
A convenient route was established for synthesizing a polystyrene-b-poly(ethylene oxide) block copolymer. Polystyryl lithium, prepared by initiating the polymerization of styrene with sec-butyl lithium, was end-capped by reaction with ethylene oxide. After isolation and characterization, the product
