dc.description.abstractThe specific retention volumes, V-g(0),blend values of the poly (isobutyl methacrylate)-poly (vinyl chloride) (PIBMA-PVC) (50%150%) and poly (4-tertbutyl styrene)-poly (vinyl chloride) (P-4-t-BS-PVC) (50%/50%) blends-probe systems were calculated between 383 and 423 K by inverse gas chromatography technique. According to these data, the thermodynamic properties such as the sorption enthalpy (Delta H-1(s)), sorption free energy (Delta G(1)(s)), sorption entropy (Delta S-1(s)), the partial molar free energy (Delta G(1)(infinity)), and the partial molar heat of mixing, (Delta H-1(infinity)) at infinite dilution were determined for the interactions of (PIBMA-PVC) (50%/50%) and (P-4-t-BS-PVC) (50%/50%) blends with alcohols and aromatics and CHCl3 by inverse gas chromatography method in the temperature range of 383-423 K. The sorption values Delta H-1(8) and Delta S-1(s) values were observed to be exothermic, and Delta G(s)(1), Delta G(1)(infinity), and Delta H-1(infinity) values were observed to be endothermic. The Delta H-1(infinity) values of PIBMA-PVC (50%/50%) and P (-4-t-BS)-PVC (50%/50%) blends-alcohols systems changed from 9.73 to 18.17 kJ/mol and from 10.00 to 16.83kJ/mol, respectively. Flory-Huggins interaction parameters, chi(12), chi(13), chi(14), chi 1(23) and chi 1(24) values of PVC, PIBMA, P (4-t-BS), PIBMA-PVC (50%/50%) and P (-4-t-BS)-PVC (50%150%) blend systems were determined at 413-423 K. In addition, chi'(23) and chi'(24) values of alcohols changed from 1.191 to 2.473 and from 1.342 to 1.839 for PIBMA-PVC (50%/50%) and P (4-t-13S)PVC (50%/50%) blends, respectively, at 413 K.
