In the polymer industry, separation equipment is required to separate unreacted monomers and solvents from polymers. In order to design such equipment, solubilities of gases and vapors in polymers are needed as fundamental data. Therefore, solubilities of twenty-one hydrocarbon gases and vapors for polybutadiene were measured by use of a gas chromatographic technique in the temperature range from 150 to 225°C under atmospheric pressure. on the basis of the thermodynamic relation between solubility and temperature, the heats of solution for these hydrocarbons were obtained. It is very helpful if the solubility can be estimated by a predictive method. The UNIFAC-FV model has been applied to calculate the solubilities of these hydrocarbon gases and vapors in polybutadiene. The solubilities calculated are in good agreement with experimental results.
