摘要：
An alternative idea of decay of free radicals in solid polymers based upon a concept of voids existing in each polymer with the mobility induced by the motion of respective polymer segments and vice versa has been put forward taking into account formal reaction kinetics. It has been shown that this approach enables the qualitative interpretation of second-order decay, stepwise decay of free radicals initiated by a stepwise increase of temperature as well as the effect of high pressure on the overall rate constant of the decay process.
