Diffusivity of polymeric solutions

Solutions of commercial and pure CMC and polyacrylamide were characterized by studying their rheological behavior. The electrochemical method, using a flow cell and the rotating disk electrode, was employed for measuring molecular diffusivities in these solutions. An anomalous behavior was found for...
