“…One of the most informative methods for determining the polarity of porous polymers is inverse gas chromatography. With this valuable tool, major surface characteristics, such as the surface energy and polarity, and Flory–Huggins interaction parameters, can be measured. In this article, we present a comprehensive study of the polarity of three porous polymers and different intermolecular interactions between the probe and each polymer's surface by inverse gas chromatography.…”

At different surface coverages (θs), the dispersion component (ΔFdisp) and specific components (induction and orientation interactions; ΔFio and donor‐acceptor interactions; ΔFda) of the sorption free energy and the polarities were calculated for three porous polymers: the microporous styrene–divinylbenzene copolymer Dowex L‐285, the microporous hypercrosslinked polystyrene MN‐200, and the macroporous styrene–divinylbenzene copolymer Polysorb‐1. Two methods were used to calculate ΔFdisp, ΔFio and ΔFda: the linear free energy relationship method and the Dong polarization method. For styrene–divinylbenzene sorbents, ΔFdisp decreased with θ, whereas ΔFio and ΔFda increased; this caused the polarity to rise. This phenomenon was caused by the sorbat–sorbat lateral interactions on the polymer's surface; these were stronger for polar molecules. In the case of hypercrosslinked polystyrene, ΔFdisp and ΔFio varied equally, and the polarity was almost constant. This trend could be explained by the absorption of the molecules into the bulk of the polymer; this prevented lateral interactions. We concluded that the lateral interactions were a function of the porous polymer's surface properties. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 44146.

Limonene is a colorless liquid hydrocarbon and had been investigated as a plasticizer for many plastics. Prediction of solubility between different materials is an advantage in many ways, one of the most convenient ways to know the compatibility of materials is to determine the degree of solubility of them in each other. The concept of "solubility parameter" can help practitioners in this way.In this study, inverse gas chromatography (IGC) method at infinite dilution was used for determination of the thermodynamic properties of DL-p-mentha-1,8-diene, 4-Isopropyl-1-methylcyclohexene (DL-limonene). The interaction between DL-limonene and 13 solvents were examined in the temperature range of 63-123°C through the assessment of the thermodynamic sorption parameters, the parameters of mixing at infinite dilution, the weight fraction activity coefficient and the Flory-Huggins interaction parameters. Additionally, the solubility parameter for DL-limonene and the temperature dependence of these parameters was investigated as well.Results show that there is a temperature dependence in solubility parameter, which increases by decreasing temperature. However, there were no specific dependence between interaction parameters and temperature, but chemical structure appeared to have a significant effect on them as well as on the type and strength of intermolecular interactions between DL-limonene and investigated solvents. The solubility parameter δ2 of DL-limonene determined to be 19.20 (J/cm3)0.5 at 25°C.
