Abstract : Certain characteristic effects of a number of halogen containing compounds, used earlier as radio-chemical structuring sensitizers for rubbers of different structure were investigated. As a result of the investigation, the following conclusions were drawn: (1) during radiolysis the sensitization effect in a number of halogen containing organic substances increases from complex aromatic structures with a large number of atoms to linear structures without double bonds and with a small number of atoms; (2) in the general case of the sensitization effect is displayed by compounds containing atoms with high electronaffinity and possessing the ability to accept thermalized electrons; (3) during the radiolysis of appropriate sensitizers one of the most important processes is the splitting of halogen, where a significant contribution is made by the dissociative electron capture reaction; and (4) it was hypothesized that the electron capture processes increase the probability of ion-molecular reactions of the primary ions with the formation of cross linking.
