The oxidation of polypropylene in the solid phase in the presence of potassium permanganate was carried out using microwave irradiation. The oxidation was achieved at time intervals of 20, 40, 60, and 90 s. According to the data available from FTIR spectroscopy, the vinylic and carbonyl groups are observed on the polymer surface. It is noteworthy that by using this method of oxidation we have saved energy and time and also less pollution has been entered into the environment by minimum oxidant consumption with maximum efficiency. © 20001 John Wiley & Sons, Inc.
