Immersion experiments with Aflas (I), poly(tetrafluoroethylene-co-pro- pylene), and Fluorel (II) (poly(vinylidene fluoride-co-perfluoropropylene)), showed greater swelling of I in nonpolar liquids and much higher swelling of II in polar liquids: over

SYNOPSIS During supposedly isothermal sorption/desorption of gases or vapors by solid polymers, latent heat effects alter local temperatures with the result that diffusion behavior may appear to be non-Fickian. Even when sorption curves are seemingly

The cure reactions of epoxy-diamine and its composites are monitored in-situ using the intrinsic fluorescence of the aromatic diamine, diaminodiphenyl sulfone (DDS). With a fiberoptic fluorimeter, in-situ cure monitoring was performed via a single fi

A series of measurements of integral n-hexane vapor sorption at 25°C and moderate activity, in polystyrene microspheres of varying radii, exhibits typical non-Fickian behavior: nonoverlap of curves of fractional uptake versus (square root of time)/r
