A numerical simulation model has been developed which enables one to examine the effects of surface mass transfer resistance on the evaluation of permeation (P*), diffusion (D), and solubility (S) coefficients from unsteady-state mass transfer experi

A model has been developed to describe the simultaneous diffusion and solvent-induced crystal formation in polymers based on the idea that crystal formation is governed by polymer chain mobility and a thermodynamic driving force. The polymer chain mo

Diffusivities of methyl acetate, methanol and water in poly(vinyl acetate) and fully and partially hydrolyzed poly(vinyl alcohol) have been measured by capillary column inverse gas chromatography and/or gravimetric sorption. Data from the literature

With the many possible composition combinations possible for copolymers there is a critical need to develop methods of predicting the properties of these materials. This paper examines the applicability of popular, current vapor–liquid equilibria p

A differential pressure adsorption unit (DPAU) has been constructed which is capable of accurately measuring isotherm data up to 2000 psia with as little as 100 mg of sample. This non-traditional adsorption/desorption method has been benchmarked by c

Mutual diffusion coefficients and sorption isotherms of methyl methacrylate (MMA) and butyl acrylate (BA) monomers in methyl methacrylate-butyl acrylate copolymer (MMA-BA) have been measured by gravimetric sorption. MMA is found to have higher solubi

An accurate (and low-cost) experimental technique has been developed to screen the effectiveness of an adsorbent in improving gas storage capacity within a pressurized vessel. Specifically, the capsule technique is shown to be effective in directly m

Hydrogen isotherms on a variety of single-walled carbon nanotube (SWNT) samples were measured using a differential pressure adsorption apparatus, which provides highly accurate data. A number of these SWNT samples were modified by a non-destructive c
