Dynamic aspects of adsorbed polymer layers: Evidence of glass-like transitions

Measurements of the mass adsorbed of polymer layers adsorbed from dilute carbon tetrachloride solutions $(\approx$1.00 mg/mL) were made as a function of time using Fourier transform infrared spectroscopy in the mode of attenuated total reflection. The general experimental approach involved surrounding an initially adsorbed polymer layer with a solution of macromolecules having a greater affinity for the surface (either silicon oxide or germanium oxide). The polymers were amorphous and flexible. The weakly adsorbing molecules in these experiments were protio and deuterio polystyrene (hPS & dPS), and polydimethylsiloxane (PDMS) in control experiments. The more strongly adsorbing molecules in these experiments were protio and deuterio poly(methyl methacrylate) (hPMMA & dPMMA), and polyisoprene (PI) in control experiments.
