Abstract: The velocity consts. of spontaneous and induced decompn. of Bz₂O₂ in pentachloroethane (I) at 93.7° ± 0.1° and in the presence of trifluorochloroethylene (II) at 78.3°, 89.5°, and 95.7° ± 0.1 were detd. The velocity of the total decompn. can be expressed in the equation -d[i]/dt = k1[i] + ki[i]n, where [i] is the concn. of Bz₂O₂, k1 is the velocity const. of unimol. spontaneous decompn., and ki is the velocity const. of induced chain decompn. Exponent n = 2 is the most suitable. The presence of II increases the decompn. of Bz₂O₂ in the soln. of I. In the polymerization without pressure of II in the soln. of I, initiated by Bz₂O₂, the effectiveness of the initiator is 0.56 ± 0.03.
