Phase equilibrium and diffusion of solvents in polybutadiene: A capillary-column inverse gas chromatography study
The capillary-column inverse gas chromatography method was used to measure the diffusion and partition coefficients of ethylbenzene, styrene, and acrylonitrile in polybutadiene (PBD) at infinite dilution of the solvents. ...
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 ...
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 ...
Solvent diffusion in amorphous polymers: Polyvinyl acetate-toluene system
In a previous publication (Tihminlioglu et al., J Polym Sci Part B: Polym Phys 1997, 35, 1279), we presented an extensive analysis of the polyvinyl acetate-toluene system. The inverse gas chromatography (IGC) technique was ...
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 ...
