This study, reports the synthesis and characterization of two new copolymers (poly[2-(pchlorophenyl)- 1,3-dioxolane-4-yl] methyl acrylate-co-styrene (PCPhDMA-co-St) and poly[2-(pchlorophenyl)- 1,3-dioxolane-4-yl] methyl acrylate-co-acrylonitrile (PCPhDMA-co-AN)). Copolymers were characterized by spectral (FT-IR, ¹H - NMR) and thermal analysis (TGA, DSC). Their thermodynamic properties, such as the adsorption enthalpy, ΔH
a , molar evaporation enthalpy, ΔHv , the sorption enthalpy, ΔH¹ s, sorption free energy, ΔG1 s, sorption entropy, ΔS1 s, the partial molar free energy, ΔG1 ∞ , at infinite dilution were studied by inverse gas chromatography. Depending on specific retention volumes, V1 ∞ , at infinite dilution were studied by inverse gas chromatography. Depending on specific retention volumes, Vg 0 , of probes the weight activity coefficients of solute probes at infinite dilution, Ω1 ∞ , and Flory-Huggins interaction parameters, between PCPhDMA-co-St and PCPhDMA-co-AN-solvents were investigated in the range of 413-453 K and 403-453 K, respectively.
