A Monte Carlo study of free radicals decay in amorphous polymers

The Monte Carlo method was used for a theoretical study of the diffusion and decay of free radicals in solid polymers. A model of amorphous polymer was built up on a tetrahedral lattice of (36 x 62 x 43) x 10" m dimen­ sions. Three types of molecular motions — kink, crank, and crankshaft — were initiated at various temperatures and changes in the concentrations of free radicals were followed as a function of the number of attempts to do motions, of temperature and density.
