Experimental data are not under the reaction rate equations by the first or the second orders and could not took into account under presented consideration. In above–mentioned work the parameter δ2 was not taking into account; however, in later investigation [30], in which the data from the above–said work concerning to the energies and enthalpies of decomposition activation were generalized, it was determined the insignificance of this factor that is in good agreement with fact that the decomposition proceeded monomolecularly since it was carried out in the presence of inhibitor.

Henceforth, the all solvents have been divided into two groups as same as in the work [20], namely, into polar and non–polar ones. In non–polar solvents under taking into consideration of the four parameters the general correlation coefficient hits in “splendid” field f(ε, n2, E, B) R = 0,992; s = 0,0912, and the values of the paired correlation coefficients are respectively equal to: f(n2)r = 0,97; f(ε)r = 0,90; f(E)r = 0,76; f(B)r = 0,83. Really, as our results in non–polar media (iso–octane, cyclohexane, carbon tetrachloride, m–xylene, toluene, benzene)) showed, the dependence of constant of iso–butyryl peroxide decompositon satisfactory correlates with the medium polarizability.

Let note, that in the strong donor, namely in pyridine, which can oxidized with the formation of N–oxides, the reaction of polymeric peroxide of azelaic acid thermolysis proceeds quicker than in other investigated solvents and the peroxide rating curves have complicate, probably, autocatalytic character. Experimental data are not under the reaction rate equations by the first or the second orders and could not took into account under presented consideration. In above–mentioned work the parameter δ2 was not taking into account; however, in later investigation [30], in which the data from the above–said work concerning to the energies and enthalpies of decomposition activation were generalized, it was determined the insignificance of this factor that is in good agreement with fact that the decomposition proceeded monomolecularly since it was carried out in the presence of inhibitor.
