• Cellulose acetate butyrate-poly(caprolactone) diol blend
• Inverse gas chromatography
• Hansen solubility parameters

The specific retention volumes, , for adsorption of 21 solute probes on the solid surface of cellulose acetate butyrate (CAB)-poly(caprolactone) diol (PCLD) blend determined in the temperature range by inverse gas chromatography were used to evaluate Hansen solubility parameters (HSP). The effect of plasticizer, PCLD, on the HSP of CAB was investigated. The three components of HSP namely dispersive , polar , and hydrogen bonding of the blend surface were compared with the CAB surface. The of CAB was increased due to the addition of PCLD, while the change in the dispersive and polar components was found to be insignificant. The three HSP were decreasing linearly with increase of temperature for the blend as well as for pure CAB. The variation of HSP with weight fraction of CAB shown that the was positively deviating from linearity whereas and were negatively deviating from linearity.
