摘要：

The technique of inverse gas chromatography has been applied to a thermodynamic study of the miscibility (compatibility) of PVC and a polymeric (polyadipate ester) plasticizer. A number of organic solvents (probes) were used to evaluate the Flory-Huggins parameters for the PVC-plasticizer interaction in stationary phase mixtures of the two components covering the entire composition range for each component (0-100%). Experiments were carried out in the range 90-120°. The interaction parameter values were found to be dependent on the chemical nature of the probes, the temperature and the composition of the mixed (binary) phase. The results predict good polymer-plasticizer compatibility for a wide range of the above mixture (up to ca 0.55 weight fraction of plasticizer). © 1990.
