ON THE ORIGIN OF THE COMPENSATION EFFECT IN THE RADIATION-INDUCED RADICAL RECOMBINATION IN POLYMERS (in Russian)
The available experimental data on the apparent reaction rate constants of the recombination of radicals in irradiated polymers show that there is a linear relationship between Ig k/sup 0/ (the apparent reaction rate constant) and E (the activation energy). This phenomenon is called the compensation effect. Depending on the crystallinity of polytetrafluoroethylene (teflon), the values of k/sup 0/ and E vary over wide limits (E from 10 to 65 kcal/mole and k/sup 0/ from 10/sup -16/ to 10/sup +6/ cm/sec). If it is assumed that the activation energy decreases with increasing temperature, that is k=k/sup 0/ exp (-E (T)/RT), a set of equations can be derived that satisfactorily explain the large variation in the activation energy and the apparent reaction rate constant for irradiated polymers.
