| Popis: | The advantage of a colloidal-heterogeneous reaction model of autooxidation of non-crystalline polymeric hydrocarbons compared to a homogeneous-liquid phase one is demonstrated by a kinetic analysis. The model considers the supermolecular organization of polymer chains into a type of spongy micelle, including a non-uniform porous zone of nanostructural scale. The mechanism of oxidation of such a micellar hydrocarbon sponge takes into account the distribution of the conjugated reacting chains in non-uniform nanophases, distinguished by the sizes and thermal fluctuational dynamics of their nanopores. Kinetic equations of macroscopic stages of the process are given. |
