Finally, a few articles have appeared on chemiluminescence of polymers. This technique has been used to detect hydroxy radicals in wood oxidation,y-irradiation effects on polyethylene, oxidation of nitrile-butadiene rubber, rubber under stress,antioxidant efficiencies in polyethylene, reactions of peroxy radicals, stereoregularity in poly(propylene), colour development in epoxy resins and structural changes in thermally aged poly(phenylene sulfide). ...

The mechanism of oxidation in the liquid phase is more difficult to study. In spite of numerous works published in this domain, it is not yet possible to define exactly the basic processes or their relative importance in oxidation reactions of liquid organic substances. However, the chemiluminescence method offers some promising applications in this field [2]. It has been used to show the participation of R- and ROj radicals in these oxidation reactions [3]. This method measures the intensity of chemiluminescence produced by the combination of ROi radicals. Absolute rates of different oxidizing reactions, efficiencies of initiators, and rate constants of radical reactions involving some antioxidants have been measured with this experimental technique [4]. A stepwise mechanism based on results from many works [1,5,6] can be suggested for the oxidation of hydrocarbons in the liquid phase. The same mechanism can be applied to thermal oxidation and to light-induced oxidation of polymers [7,8] the main steps are as follows ...
