A solid state 13C nuclear magnetic resonance investigation of the thermal degradation of a poly(ethylene glycol) and poly(vinyl alcohol) binder in an alumina ceramic



Cross polarization and magic angle spinning 13C nuclear magnetic resonance spectroscopy (CP-MAS 13C NMR) has been used to investigate the thermal degradation of poly(ethylene glycol) (PEG)-alumina, poly(vinyl alcohol) (PVA)-alumina, and a mixture of 6% PEG and 0.5% PVA in alumina. Samples were prepared by thermally treating each polymer at 450°C to remove pre-specified weight losses. The results showed that the polymer chains of both PEG and PVA thermally degraded as postulated in previously published mechanistic studies based on volatile degradation product analyses. The CP-MAS 13C NMR spectra of PEG and PVA in alumina showed that the two polymers thermally decomposed independently of each other.
