CONCEPT OF MOBILE VOIDS IN THE INTERPRETATION OF DECAY OF FREE-RADICALS IN SOLID POLYMERS

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