Abstract
Diffusion of polystyrene latex and the sodium salt of fluorescein represent the macroscopic and microscopic limits, respectively, of probe diffusion in aqueous hydroxypropylcellulose. In both cases, chemical complexities, such as surface interactions leading to probe aggregation or the solvation characteristics of the polymer matrix, can obscure the general physical information that can be extracted. But when these details are taken into account, a rational picture of probe diffusion in hydroxypropylcellulose begins to emerge. At the same time certain observations, especially the rapid decay mode present in some dynamic light scattering experiments, remain difficult to interpret.
