A model for calculating of the change in the basic thermodynamic 
characteristics of a sorbent (internal energy and entropy) with the 
phenomenological-thermodynamics method has been developed. Calculations 
for the systems polycarbonate-carbon dioxide and polymethylmethacrylate-carbon 
dioxide have been carried out.
