Abstract
Net retention volumes, VN, 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 323.15–393.15 K. The VN 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 VN 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.
