Three classes of polymer particles are investigated by selective liquid sorption from 1-propanol-water mixtures. Class 1 are gel polymerized polar (hydrophilic) dextran spheres (Sephadex), class 2 are macroreticular polar (hydrophilic) ion exchangers (Chelite) and class 3 are emulsion polymerized latex particles. The enthalpy of displacement isotherms accompanying the sorption processes are determined by different calorimetric techniques (flow microcalorimetry, titration calorimetry, immersion calorimetry). The enthalpy isotherms reveal the differences in polarity of the polymer network.
