Abstract

The solubility and diffusivity of water at 100° C, 95% relative humidity were studied for 14 stoichiometric epoxide-amine networks based on epoxide or amine mixtures. Neither the packing density nor the glass transition temperature nor the crosslink density seemed to play a significant role. The water absorption is essentially linked to the concentration of polar structures, but also decreases with the extent of intramolecular hydrogen bonding. This can be accurately predicted using a simple additive relationship. The diffusivity decreases with the hydrophilicity and packing density, but in a complex way probably involving the nature of hydrogen bonds between the water and the substrate.
