摘要：
The control of reactivity of several bis(N-glycidylsulfonamides) by aromatic substituents is presented. Therefore, disulfonamides with electron-withdrawing or electron-donating aryl moieties and a linear, branched, or oxygen-substituted spacer are synthesized and further N-alkylated with epichlorohydrin. Their curing times with N,N-dimethyl aminopropyl amine in comparison with standard bisphenol A diglycidyl ether are measured by oscillatory rheology. A dependence of curing time with the Hammett sigma-value is found.
