摘要：

The specific retention volumes, , for 21 solute probes were determined on a 1:1 cellulose acetate propionate (CAP)-poly(caprolactone)diol (PCLD) blend in the temperature range 343.15413.15K by inverse gas chromatography. The retention diagrams of solutes revealed a phase transition in the blend at about 393K, and it was identified with the glass transition temperature. The CAP-PCLD blend is in the solid phase up to 393K, hence the Hansen solubility parameters (HSP) of the blend surface were calculated using . The three components of the HSP, dispersive, , polar, , and hydrogen bonding, , for the blend surface decreased with increase of temperature. The HSP of the blend were compared with the corresponding values obtained on pure CAP surface: and values are lower in the blend than in the pure CAP, whereas is higher in the blend than in the pure CAP. The effect of the addition of PCLD on the HSP of CAP is discussed.
