Polyurethane rigid foam shows substantial changes in its photoacoustic absorption spectra (PAS) on heating in the presence of air. These spectral changes are due to conjugated structures and quinone-imide formation, formed during degradation. The mechanism of degradation appears to be free radical i

Immediately after heating rigid foam polyurethane (PU) at 165"C, it degrades in accordance with the degradation mechanisms suggested by Abu-&id et al. in earlier publications. However, after three days all photoacoustic spectra (PAS) bands indicative of PU degradation almost disappeared, and the sam
The degradation of polyaniline at anodic potentials was studied with in situ UV-Vis spectroscopy of polymer-coated ITO glass electrodes. Spectral changes at high potential values were observed and discussed. Degradation follows first-order kinetics, with rate constants ranging from 8.40 ϫ 10 Ϫ6 to 2
