Diffusion of sulfur dioxide in epoxy resin of aliphatic diglycidyl ether was studied performing differential sorption kinetic measurements at temperatures ranging from 1°C to 45°C and activities varying from 0.12 to 0.55. The diffusion of sulfur dioxide appears to be Fickian over the entire temperature range studied. There is a marginal increase in the diffusion coefficient with increase in concentration. The diffusion coefficients evaluated from both “small times” data and “large times” data are in reasonable agreement.
