Poly(ethylene oxide) (PEO) of molecular weight (Mw) ca 5 x 106 and its complex with NaCNS have been thermally degraded at temperatures in the range 320-330 Β° . Examination of the polymeric residues shows that in both cases there is a precipitous decrease in M, during degradation consistent with a ra
TGA curves for the thermal decomposition of PS in nitrogen (dashed line) and air (solid line). Heating rates of 9.0 and 8.2 K N min -1 for nitrogen and air, respectively.
The oxidative thermal degradation of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) at 150Β°C in air was studied. The weight loss was determined, and the structure of the residual polymer investigated using NMR. In PEO, the only significant structural changes were the formation of formate
