| Popis: | The specific retention volumes, V0g, for 21 solute probes in a cellulose acetate phthalate (CAP)–polycaprolactonediol (PCLD) blend were determined by inverse gas chromatography (IGC) in the temperature range 323.15–413.15 K. The retention diagrams drawn between lnV0g vs. revealed the presence of the glass transition temperature at about 373 K. Therefore, the Flory-Huggins interaction parameters at infinite dilution, χ∞12, were calculated using V0g values in the temperature range 373.15–413.15 K. The χ∞12 values decreased with increase of temperature for all the solutes. Further, the χ∞12 values decreased with decrease of chain length of n-alkanes whereas in 1-alcohols the trend was reversed. The Hansen solubility parameters (HSP) were determined in the temperature range 373.15–413.15 K following the Flory-Huggins solution model. The dispersive and polar components of the HSP decreased with increase of temperature whereas the hydrogen bonding component slightly increased with increase of temperature. |
