STUDY ON THE SORPTION AND DESORPTION OF N-PENTANE IN POLYSTYRENE AND POLYPROPYLENE

摘要

This paper studied the sorption/desorption of n-pentane in polystyrene and polypropylene using the sheet samples. The solubility of n-pentane in PS and PP was measured. And the concentration-dependent diffusivity of n-pentane in PS and PP was computationally modeled. Results exhibit that the simulated profiles match well with the experimental data while the penetrant concentration is above 30%.
