## Abstract A special model system based on a diglycidylester (1) and 4,4β²βdiaminodiphenylmethane (2) was used to characterize the network structure of epoxy resins. Networks with cure degrees of 0,72 to 0,82 were prepared. These networks could be cleaved by hydrolysis after curing, and the network

Water-sorption isotherms have been determined for some bisphenol-A-type epoxy resins cured with either 4,4'-diamino diphenyl methane (DDM), phthalic anhydride, or polyamide, Versamid 115. The absorption isotherms for the diamine-cured resin are reversible and that at 0.2"C is linear for the whole ac
Changes in microstructure and mechanical properties are investigated as a function of epoxy-amine stoichiometry. The epoxy-amine system studied exhibits a two-phase structure consisting of a hard microgel phase and a dispersed phase of soft, unreacted and/or partially reacted material. The size dist
