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
## Abstract The kinetics of the thermal and microwaveβassisted oxidative degradation of poly(ethylene oxide) were determined with potassium persulfate as the oxidizing agent. Gel permeation chromatography was used to determine the variation of the molecular weight with time. The degradation was stu
