Solvent diffusion in amorphous polymers: polystyrene-solvent systems
The inverse gas chromatography (IGC) technique was used to obtain the partition and diffusion coefficients of solvents in polystyrene over a wide range of temperatures. Infinite dilution experiments were performed with ...
Influence of swelling and diffusion-induced convection on polymer sorption processes
(American Institute of Chemical Engineers, 2002-09)
Unsteady-state sorption of a vapor or liquid by a polymer is modeled to include the influence of the moving phase boundary associated with the polymer swelling and diffusion-induced convection. A formulation presented ...
