On the other hand; there is no unifying theoretical formulation for glassy polymers. There is not even a complete classification of the various anomalous effects. Glassy polymers respond slowly to changing conditions; and most of the anomalous effects are directly related to this. For example; the changing polymer structure influences the solubility and diffusional mobility. This leads to diffusion coefficients which can depend not only nonlinearly on the state of the system; but also on the previous history of the system; and sometimes even on previous rates of change of the system [1-4]. Internal stresses can be induced due to *Supported in part by the U.S. Army Research Office (Durham) under Contract DAAG29-81-K-0107 and by the National Science Foundationu nder grant MCS-8205407;
