摘要：

Physical processes stipulating photoinitiation of polystyrene destruction under influence of powerful UV-radiation treatment are considered. The experimental results on its photolysis at UV-irradiation in different spectral ranges are given confirming the decisive role of triplet-triplet transfer of excitation energy from benzene rings to simple bonds, and triplet-triplet annihilation on the initial stages of photodestruction.
