The present study has shown that the parameter ϵ can be accepted as a characteristic of polymer (stabilized or nonstabilized) resistance to thermooxidative degradative action. This parameter can characterize the number of steps number required for a random walk (molecule or atom of oxidant) to achieve the reactive center of a polymer macromolecule. The main structural factor for defining polymer resistance to thermooxidative degradation is effective spectral dimension. It also shows the physical sense of the term structural stabilization . © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 100: 2614–2618, 2006
