A structural model of an accessibility of polycarbonate melt to thermooxidative degradation processes

摘要

It is shown that the "accessibility" of a polymer for oxidation is the only structural factor and quantitative estimate within the framework of the fractional derivation. The oxidation rate of the "accessible" part of a macromolecular coil is independent on its structure, which allows to assume its dependence only on the chemical constitution of polymer.
