dc.description.abstractIn this work, some thermodynamic properties of poly (cyclohexyl methacrylate) were studied by inverse gas chromatography (IGC). For this purpose, the polymeric substance was coated on Chromosorb W and which was filled into a glass column. The retention times (tr) of the probes were determined from the interactions of poly ( cyclohexyl methacrylate) with n-pentane, n-hexane, n-heptane, n-octane, n-decane, methanol, ethanol, 2-propanol, butanol, acetone, ethyl methyl ketone, benzene, toluene and o-xylene by IGC technique. Then, the specific volume (V0g) was determined for each probe molecule. By using (1 /T; lnV0g) graphics, the glass transition temperature of poly(cyclohexyl methacrylate) was found to be 373 K. The adsorption heat under the glass transition temperature (?Ha), and partial molar heat of sorption above the glass transition (?Hs1)' partial molar free energy of sorption (?Gs1) and partial molar entropy of sorption (?Ss1) belonging to sorption for every probe were calculated. The partial molar heat of mixing at infinite dilution (?H?1), partial molar free energy of mixing at infinite dilution (?D?1), Flory-Huggins interaction parameter (??12) and weight fraction activity coefficient (a1/w1)? values of polymer-solute systems were calculated at different column temperatures. The solubility parameters (?2) of the polymer were obtained by IGC technique.
