The Diffusion and Sorption of Gases and Vapours in Glassy Polymers
H. B. Hopfenberg,V. Stannett +1 more
TL;DR: In this article, it was shown that diffusion in the glassy state is characterised more accurately by anomalous or complicated behaviour than it is by a simple, unifying mathematical or conceptual model.

The diffusion and solution of gases in highly crosslinked copolymers
TL;DR: In this paper, a study was made of the diffusion and solution of helium, hydrogen, neon, argon, krypton, oxygen, nitrogen, methane and carbon dioxide in a series of highly crosslinked copolymer membranes in the temperature range 40° to 80°C.

Diffusion in polymer-diluent systems
TL;DR: In this article, the authors discuss some selected topics with which they have a relatively greater acquaintance but which they feel are of fundamental importance for understanding the current situation in this field of polymer research.

Viscosity and glass temperature relations for polymer-diluent systems
F. N. Kelley,F. Bueche +1 more
TL;DR: In this paper, free volume expressions are derived from free volume considerations which predict the concentration dependence of viscosity and glass temperature for polymer-diluent systems, and general agreement with theory is found over broad ranges of concentration.

Diffusion Coefficient, Solubility, and Permeability for Helium in Glass
TL;DR: In this article, a method for simultaneously measuring the diffusion coefficient, solubility, and permeability for a given gas in a single sample of solid material is described, which utilizes solutions of the diffusion equation for both plane and cylindrical geometry.
Journal ArticleDOI
Helium Diffusion through Glass
TL;DR: In this article, the authors used a mass spectrometer to measure the gas flow rates of 20 different glasses and found that a better correlation exists between log permeation rate and mole percent of glass network former (SiO2, B2O3, and P2O5) content than exists between the two metrics.
