## 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
Atactic polypropylene was oxidized in solution in the presence and absence of radical initiator over the temperature range of 140' to 200'C under oxygen pressure of 3.3 to 12.4 kg/cm2, and the effects of metal catalyst and additives on the rate, products, and change in molecular weight distribution
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.
