✦ Synopsis

Secondary multiple cool flame appearing under certain conditions during thermooxidation of polypropylene was interpreted on the basis of oxidation of the polymer surface being influenced by changes in the direction of the temperature gradient. The average period of the oscillation process, directly proportional to the amplitude of the first oscillation, expresses the effect on the oscillation process of all important factors such as the oxygen concentration, rate of delivery of volatile oxidation products and temperature of a cool flame in the gas phase.
