Abstract
The adsorption of polybutadiene (PBR) on alumina and silica gel was studied at different temperatures from cyclohexane and toluene solutions. It shows that the adsorption process was dependent on temperature and solvent. The adsorption isotherm and the thermodynamic quantities of adsorption were determined and it was observed that the adsorption process from both solvents was similar and the amount of adsorption increased as temperature decreased. The silica gel-cyclohexane system was more exothermic than all other systems and was also relatively more ordered.
