Abstract:  The influence of 1,3-diphenyl-1-butene, 1,2-dibromo-1,3-diphenylbutane, and 1,3-bis(4-nitrophenyl)-l-butene on the phototransformation reactions of polybutadiene in a thin film was studied. Qualitative differences in the effect of the substituents bonded to a molecule of the dimer of styrene were disclosed for bromo and nitro derivatives. The presence of 1,3-diphenyl-1-butene and its dibromo derivative produces an acceleration of the photooxidation reaction of polymer resulting in a reduction in length of the main chain in the soüd phase. For 1,3-bis(4-nitrophenyl)-1-butene, a decreased rate of photooxidation reaction, prolongation of induction period, and decrease in the content of oxidation products is to be observed.
