Real time dielectric measurements of network formation in a crosslinked epoxy resin system

Real time dielectric measurements are reported on the cure of the diglycidyl ether of bisphenol A (DGEBA) and diamino diphenyl sulfone (DDS) over a temperature range from 393 to 443 K. The measurements were performed over a frequency range from 10 -1 to 10 5 Hz and spectra were collected at regular intervals during the period of cure
