The authors previously reported work on the kinetics and mechanism of the uncatalyzed thermal oxidation of isotactic polypropylene. The data, obtained form infrared absorption spectra of the carbonyl region, was utilized in developing the theoretical expressions presented. This paper summarizes this work and presents further evidence which substantiates the derived expressions. The additional evidence is obtained from infrared absorption spectra involving the apparent hydroperoxy region and from measurements on the rate of formation of volatile products. Some recent pertinent literature is also discussed.
