Catalysis of the reaction of kinetic chains transfer and freak is important property of
solid-phase reactions and is of great importance in the processes of ageing and stabilization of
polymers. Lowmolecular products of oxidation and destruction, dissolved in solid-phase
polymer may react with macromolecules. Lowmolecular radicals being formed easily diffuse
and, reacting in the other place, transfer free valency along the polymer volume, transmitting
kinetic chains according to diffusive mechanism. Since diffusion of macroradicals takes place
much easier in amorphous and intercrystalline regions of polymer (lowmolecular products of
