摘要：

Inverse gas chromatography was used to study polymer/solvent interactions at infinite dilution. Consideration was given to the effect of solute sample size, gas flow rate, and the chemical nature of the substrate. Experimental results are presented for a wide variety of organic solvents, both polar and nonpolar, with polybutadiene (353-373 K) and polyisoprene (328 K). Weight fraction activity coefficients, Flory-Huggins chi parameters, and heats of solution have been calculated from measurements of the retention volumes. The same general solubility behavior was observed with both polyisoprene and polybutadiene.
