Gas chromatography (GC) retention behavior of atactic and isotactic poly(vinylisobutyl ether) stationary phases has been studied in the temperature range 30–90°C using 16 solutes which include various alkanes, alkylbenzenes, and chlorinated aliphatic hydrocarbons. The bulk sorption equilibrium retention data have been employed to derive various thermodynamic quantities at infinite dilution of solutes in the polymers, viz. , χ, χ * , χ H , χ S , X 12 , δ H S , h 1 ∞ . Their dependence on temperature, polymer structure, and chemical nature of solutes has been discussed.
