Özet:

 

Some thermodynamic quantities were obtained for the interactions of  poly [2-(3-phenyl -3- methylcyclobutyl)-2-hydroxyethyl  methacrylate-co-methacrylic acid] Poly (PCHEMA-co-MA) with alcohols, ketones, acetates,  aromatics and n-alkanes by inverse gas chromatography  in the  temperature range of 150-180oC. The specific retention volumes, Vgo,  weight fraction activity coefficients of solute probes at infinite  dilution,  W1\infty  and Flory-Huggins thermodynamic interaction parameters,   c12\infty  between polymers and solvents were determined.  The partial molar  free energy,  DG1\infty , the partial molar heat of mixing,    DH1\infty , at infinite  dilution and the solubility parameters of the polymer,  d2   , were  calculated. The copolymer was characterized by  1 H-NMR, FT-IR   and DSC analyses.
