Studies of chain scission of butyl rubber (1.75% by weight of isoprene) have been extended. Experiments showing chain scission as function of various oxygen and nitrogen pressures, temperatures, and near‐ultraviolet light intensity are presented. The experimental data agree with the mechanisms assumed in previous work or with elaborations of such mechanisms to include additional factors (ultraviolet radiation etc.). NO2 retards chain scission in presence of near‐ultraviolet light. Photo‐oxidation in presence of relatively high and low nitrogen dioxide pressures, respectively, show experimental curves of opposite curvature; these data have also been evaluated in terms of méchanism. Arrhenius equations are presented for experiments related to the different reaction mechanisms.
