Retention factors of several oligomers of ethylene glycol (12- to 18-mer), methyl methacrylate (8- to 12-mer), and styrene (4- to 12-mer) were measured by supercritical fluid chromatography in an open tubular capillary column within 371-431 K and 13.9-31.1 MPa. The results were used to obtain the partial molar volumes of the oligomers in carbon dioxide and the Krichevskii functions describing the oligomerCO2 interactions.
