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.
