In X-and Y-irAdiated polycrystalline glycines the.radiolytic behaviour is dependent on the crystal structure and/or the extent of deuterium Iabelling. This is due to a selective transformation of the formed 'CH-COO' radical into the H$'-'CH-COO-radical and not to a selective decay of the 'CH2 -COO'

The influence of pressure on the decay of free radicals in irradiated PMMA has been investigated by ESR over the ranges 80-130 Β° and 1-13,000 atm. Dependence on pressure of both the rate constants and activation energies for decay has been determined. The influence of pressure on the mechanism of de
Free radicals were generated in isotactic polypropylene by gamma-irradiation. The samples were annealed at pressures between 1 and 8000 arm and temperatures between 60 and 110 Β°. The concentration of free radicals was estimated by the ESR method. The rate constants of free radical decay were determi
