Summary: | Some thermodynamic properties, such as the sorption enthalpy,
sorption free energy,
sorption entropy;
the partial molar free energy,
and the partial molar heat of mixing,
at infinite dilution were obtained for the interactions of poly[(2-phenyl-1, 3-dioxolane-4-yl)methyl methacrylate-co-butyl methacrylate] (PDMMA-co-BMA) with alcohols by the inverse gas chromatography method in a temperature range of 323 to 453°K. The specific retention volumes, Vg
o
; the weight fraction activity coefficients of solute probes at infinite dilution,
and Flory-Huggins interaction parameters,
between polymers and solvents were determined. Also, the solubility parameters, δ
2
, of (PDMMA-co-BMA) were found to be 6.80 (cal/cm
−3
)
0.5
and 7.80 (cal/cm

from the slope and intercept of [(
equation, at 403°K, respectively. The glass transition temperature, Tg, of the polymer was found to be 370 K by inverse gas chromatography. |
