✦ Synopsis

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. Copyright 1999 Academic Press.

## Abstract We describe non‐radiative energy‐transfer experiments to measure the rates of polymer interdiffusion in P(MMA‐__co__‐BA) latex films formed in the presence of poly(vinyl alcohol) (PVOH). PVOH had relatively little effect on the initial efficiency of energy transfer, even when the amount
