摘要：

The technique of ATR (attenuated total reflection) has been used for the study of the adsorption kinetics of anionic polymers onto a monolayer of cationic amphiphiles. This is, to the best of our knowledge, the first in situ measurement of the polymer adsorption onto a Langmuir film. The polymers are adsorbed in two steps: the adsorbance of the polymer was monomolecular initially and increased with adsorption time, until a final equilibrium plateau was reached. The equilibrium adsorbance increased with molecular weight of a polymer, which indicates that a significant portion of the polymer is in the loop or the tail form.
