A special model system based on a diglycidylester (1) and 4,4′‐diaminodiphenylmethane (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 functionality and its distribution were characterized by chromatography. The results are in good agreement with predictions from branching theory, no indication of a deviation from statistics could be found.
