Radical reactions in the photodeccomposition of benzoyl peroxide in solid polycarbonate

Conclusions The decomposition of benzoyl peroxide in solid polycarbonate under UV irradiation is a monomolecular chain process.This process is accompanied by the intensive formation of colored products. After complete decomposition of the benzoyl peroxide, this process passes over to a new initiator stage for continued photoreaction of the polycarbonate. A reaction scheme is proposed which involves chain radical reactions, some with participation of polycarbonate macroradicals.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 66–74, January, 1977.
