The transport of small molecules in polyolefins is a subject of both technical and commercial
importance. It is technically important because the factors, such as morphology and …

Attenuated total reflection (ATR) FTIR spectroscopy has been used to study the diffusion of
water into sulfonated poly (ether sulfone) films as a function of film thickness, preparation …

Over the past 2 decades, the use of time‐resolved Fourier transform infrared/attenuated total
reflection (ATR) spectroscopy for the measurement of diffusion in polymers has grown. ATR …

Rutherford backscattering spectrometry (R BS) has been used to measure the volume
fraction versus depth profiles of iodohexane vapour diffusing into glassy polystyrene. At …

Rutherford backscattering spectrometry was used to measure the front velocity V and the
local volume fraction∅(x) versus depth x of iodohexane in polystyrene as a function of …

This survey of recent studies correlates the transport kinetics and equilibria of organic
vapors and liquids in glassy polymers with the molecular size, interaction parameter, and …

The diffusion of water into SPEES/PES polysulfone thin films, with different degrees of
sulfonation, has been studied in situ using the FTIR-ATR (attenuated total reflection) …

The variation of nuclear magnetic resonance (NMR) relaxation parameters (T1, T2) within a
polymer during swelling, limits the absolute accuracy with which liquid concentration profiles …

An improved method for obtaining cross-sectional images of thin polymer films by
transmission electron microscopy is described. Two examples are described in order to …

The effect of temperature on the kinetics of methanol transport in PMMA has been
investigated for the first time in spherical sample geometry over the temperature range of 25 …
