The mean diffusion coefficients, D, for maltose-water mixtures close to the glass transition temperature, Tg, were measured using a gravimetric method during desorption of water. The mass loss showed a linear dependence on the square root of time, indicating a Fickian diffusive process. At 300 K, an

The bonding of amorphous polystyrene (PS) and poly(2,6-dimethyl-1,4phenylene oxide) (PPO) was conducted over a broad range of time and temperatures, but always below the (bulk) glass transition temperature (T g ).
