Isotherms for the adsorption of nitrogen and argon on poly(methylmethacrylate) were obtained at three temperatures over a pressure range from a few microns to the saturated vapor pressure of the adsorbing gas. Differential and integral enthalpies and entropies were calculated and indicate a heterogeneous surface with adsorption energies higher than those observed for unsubstituted hydrocarbons. Clustering functions were calculated and indicate that the adsorption occurred in clusters throughout the range investigated.
