Accumulation of radicals in the photodecomposition of polypropylene hydroperoxide

Summary According to EPR data, upon UV irradiation both in the near (<300m) and the far (>300m) region decomposition of polypropylene hydroperoxide take place, accompanied by the accumulation of radicals at rates of 1.5·10¹⁴ and 6·10¹⁴ particles per minute, respectively.In conclusion I must thank M. V. Alfimov and V. A. Smirnov for their help in obtaining the spectra.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 12 p. 2212–2214, December, 1964
