摘要：
The authors have analyzed the polycondensation of the system based on diglycidyl ether of bisphenol A (DGEBA) crosslinked with 4,4 prime -diaminodiphenylsulfone (DDS) in the absence of or presence of a catalyst, benzyldimethylamine or BF//3 complex. Chemical data obtained with Fourier transform infra-red spectroscopy (FTi. r. ) and solid state **1**3C n. m. r. with CP MAS have enabled the various chemical species in the network to be qualitatively detected and quantitatively assayed. The molecular results related to reaction mechanisms, obtained as a function of the per cent catalyst present, were correlated with thermal (T//g), dielectric ( beta relaxation) and moisture absorption data.
