proton spectrumThe application of Fourier transform two-dimensional n.m.r. spectroscopy to the study of the epoxy resin monomer, tetraglycidyl methylenedianiline, TGMDA, is reported. The combination of homonuclear proton 2D-J resolved and shift correlated SUPERCOSY experiments permits the complete ...
The monomeric diglycidyl ether of bisphenol-A cured with methylenedianiline has been studied by pulsed NMR. Values of the proton relaxation times T 1 , T 1 p , and T 2 have been measured over the temperature range 160 to 200°C. The system was studied after being fully postcured at 180...

The curing process, during which the monomeric diglycidyl ether of bisphenol-A is cured with 4,4′-methylenedianiline, has been studied by pulsed NMR. Values of the proton relaxation times T 1 , T 1ρ , and T 2 have been measured as a function of time as the resin system cures at co...
