Abstract
The role of long-chain structure of polymer in the polymer oxidation kinetics is discussed. The chain reaction of a polymer oxidation includes the same steps as the oxidation of its low-molecular analogues but the rates and the roles of these steps may differ considerably. The chain propagation step may proceed either intramolecularily, or intermolecularily. Great role in oxidation of some polymer play low-molecular free radicals formed in the reaction. Irregularity of polymer structure results in irregularity of low-molecular compounds, oxygen including, distribution over the polymer volume. All these phenomena affect the polymer oxidation kinetics.
