AbstractThe packing densities (Van der Waals volume/molar volume) were determined at 293 K for various epoxide–amine stoichiometric networks. They are noticeably higher than those of linear polymers except strongly hydrogen bonded ones polyamides, poly(vinyl alcohol). By extrapolation of the dilatometric data, it was found that the packing densities at the frontiers of the glassy state (0 K andTg) of the epoxy networks are comparable to those of linear polymers having the same theoretical hydrogen bond density (polyamides). However, for a given packing density at 0 K, the packing density atTgis higher for a network than for the corresponding linear polyme
