The kinetics of chain initiation during the auto-oxidation of some unsaturated compounds (methyl linoleate, allyl acetate, allyl propyl ether, styrene, α-methyl styrene, butyl acrylate, butyl methacrylate, ethyl cinnamate, trans-1,2-diphenylethylene, trans,trans-1,4-diphenylbutadiene-1,3) in solvents of different polarity was studied at temperatures 343–383 K. The data array comprised of chain initiation rate constants of bi- and trimolecular reactions was obtained. It was shown that in some cases, the polarity of the medium is the key factor defining the initiation mechanism.
