Processing of polymers with supercritical fluids
(Wiley-VCH Verlag, 1999-11)
The removal of impurities, such as residual solvents, unreacted monomers, catalysts, and side-reaction products from polymers represents an important step in polymer processing. Conventional devolatilization techniques for ...
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 ...
Solvent sorption in a polymer-solvent system - Importance of swelling and heat effects
Sorption experiments are often conducted in gravimetric sorption columns where several deviations from ideal conditions could potentially occur. For example, heat effects due to solvent sorption, errors introduced due to ...
Errors associated with swelling in the analysis of polymer-solvent diffusion measurements
Sorption curves are generated from a mathematical model which includes the influence of the polymer swelling for unsteady-state sorption of a vapor or liquid by a polymer. To investigate the simultaneous effects of the ...
