Diffusion-controlled random termination

Values for activation energies of propagation, initiation, and termination are given in Table 6 for polychlorotrifluoroethylene, poly(a-methylstyrene), polystyrene, and poly(methyl methacrylate), assuming a random initiation mechanism. The energy for combination Et is assumed to be zero in the gas phase, hut in a viscous condensed medium it is considerably above zero, about 83.7 kJ/mol (20 kcal/mol) has been reported for poly(methyl methacrylate) (63). Termination is a diffusion-controlled process, and the activation energy for the diffiision of... [Pg.246]
