The compatibilities of the systems poly(vinylidene chloride-vinyl chloride 80:20)/polyadipate ester and poly(vinylidene chloride-vinyl chloride 80:20)/tri-iso-nonyl trimellitate have been studied in the range 90-110-degrees-C using inverse gas chromatography (IGC). The retention behaviour of the polymer/plasticizer mixtures covering the entire composition range for each component was characterized for 10 probes of different chemical nature. In agreement with previous work, the IGC-derived interaction parameters (X23+) showed an apparent dependence on the chemical nature of the probe, blend composition and temperature. The results predict good polymer/plasticizer compatibility up to c. 0.40 weight fraction of plasticizer for poly(vinylidene chloride-vinyl chloride 80:20)/polyadipate ester blends and to c. 0.50 for poly(vinylidene chloride-vinyl chloride 80:20)/tri-iso-nonyl trimellitate blends.
