## Abstract __N,N__‐bis(2,3‐epoxypropyl) aniline (__N,N__‐diglycidylaniline, DGA) and an intermediate of its synthesis, __N,N__‐bis(2‐hydroxy‐3‐chloropropyl) aniline (__N,N__‐dichlorohydrin of aniline, DCHA), were analyzed by GPC and HPLC. The main impurities were isolated by semipreparative HPLC a
## Abstract 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
