Infrared spectroscopy in the mode of attenuated total reflection (ATR) is a well-developed method for sampling the thin volume of materials within a few micrometers of an ATR prism surface. The method does not appear to have been applied previously to studying adsorption of high polymers from solution. In this report, we demonstrate the utility of the ATR method for studying the kinetics of polymer adsorption in situ at the solid-liquid interface. A feature of these experiments is that kinetics of displacement of surface-bound polymer by other polymers originally in free solution were far slower than kinetics of adsorption onto originally bare surface. These experiments illustrate that it is possible to measure the kinetics that underlie an overall adsorption equilibrium.
