The objective of this research is to probe the mobility of                 polymers at well-characterized single solid surfaces.  By                       measuring the kinetics with which polymers first adsorb to a                    surface and then exchange with labelled polymers originally in                  free solution, we will seek to understand the characteristic                    rates and mechanism of mobility of polymers in thin interfacial                 regions.  Experimental variables of interest will include                       molecular weight, solvent quality, solution concentration, and                  polymer topology.  The self-exchange of polymers with the same                  number of segments will be a special concern.  The method of                    investigation is infrared spectroscopy in attenuated total                      reflection.  The results will be correlated with modern physical                theories of polymer behavior, and may find application in                       chromatography, colloidal stability and flocculation,                           lubrication, and film formation.
