摘要：

The long-time approximation for the time-dependence concentration of solvent into film is derived. The interdiffusion coefficients for different temperatures and the different polystyrene molecular weights were calculated by using asymptotic formulae and time-dependence concentrations of solvent into polymer films. The apparent activation energies of interdiffusion were estimated. (C) 1999 Academic Press.
