Description

Fourier transform infrared, nuclear magnetic resonance (NMR), and electron paramagnetic resonance (EPR) experiments were performed to characterize the cure states of 4,4'-bis (3-ethynylphenoxy) diphenylsulfone. Measurements were performed at selected times during isothermal cures at 403 K, 423 K, and 453 K. Independent cure-state parameters were derived from IR absorbance changes, IR frequency shifts, H-1 NMR relaxation times, NMR magic-angle spinning spectral areas, and EPR-determined concentrations of free radicals produced during polymerization. 12 references
