dc.description.abstractIn this study, some thermodynamic properties of poly(benzyl methacrylate) (PBzMA) were studied by using the inverse gas chromatography (IGC) technique. The retention times (t(r)) of probes were determined from the interactions with PBzMA of four groups of solvents with different chemical natures and polarities. Then, specific volume (V-g(0)) values were determined for each probe molecules. The glass transition temperature (T-g) of PBzMA was found as 323 K from inverse gas chromatography measurements. Under the glass transition temperatures adsorption heat (Delta H-a) and above the glass transition molar heat (Delta H-1(S)), free energies (Delta G(1)(S)) and entropies (Delta S-1(S)) belonging to sorption for every probe were calculated from inverse gas chromatography measurements. The partial molar heat (Delta H-1(infinity)), partial molar free energy (Delta G(1)(infinity)) Flory Huggins interaction parameter (chi(infinity)(12)) and weight fraction activity coefficient (a(1)/w(1))(infinity), values for infinite dilute solutions were calculated for polymer probe systems. The solubility parameter (delta(2)) of the polymer was obtained from the slope and intercepts of Flory Huggins interaction parameter (chi(infinity)(12)) graphs with solubility parameters (delta(1)) of probes.
