Sorption with Oscillations in Solid Polymers
Among the varieties of anomalous behaviors exhibited during the diffusion of vapors in polymers, sigmoidal sorption curves and case II diffusion are commonly cited. in previous work authors have attempted to explain sigmoidal behavior as due to the elastic stresses experienced by polymers due to swelling by the penetrants. This note shows that expression for flux does a reasonable job of unifying oscillations and overshoots in a wide variety of cases.
