Abstract
Three types of ageing (thermal oxidation, radiochemical ageing and hydrolyt ic ageing) have been applied to a series of epoxy networks which can be use d for the embedding of low activity radioactive wastes. The effects on the chemical composition and structure were studied and related to the evolutio n of the gas diffusion properties of these networks. In the case of thermal oxidation, the detailed kinetic study of the degradation and the measureme nt of O-2 solubility and diffusivity allowed precise modelling of the oxida tion profile.
