摘要：

Net retention volumes, V-N,V- of n-alkanes and five polar solute probes on cellulose acetate butyrate - Polycaprolactonediol have been determined by inverse gas chromatography technique in the temperature range 323.15-393.15K. The V-N values of n-alkanes are used to calculate the dispersive component of surface energy of the blend. The values are decreasing nonlinearly with increase of temperature. The V-N values of the five polar solutes are used to calculate the specific components of the enthalpy of adsorption and entropy of adsorption . The values are used to calculate Lewis acidity constant and basicity constant, which are 0.143 and 0.744, respectively.
