✦ Synopsis

The influence of pressure on the decay of free radicals in irradiated PMMA has been investigated by ESR over the ranges 80-130 ° 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 decay of free radicals has been discussed.

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 °. The concentration of free radicals was estimated by the ESR method. The rate constants of free radical decay were determi

## Abstract The decay of free radicals in irradiated PMMA subjected to high pressures has been studied by the method of ESR. The rate constants and activation energies has been determined for the decay of free radicals at the pressures of 5000 and 10,000 atm over the temperature range of 100–170°C.
