The processes occurring in oligomeric systems under conditions of polymerization and accelerated aging induced by UV light were investigated using the method of IR spectroscopy. It was shown that photochemical degradation occurs primarily upon UV-light irradiation of cured epoxy acrylates at the ester groups and results in the formation of peroxyacids. The principal possibility of introducing the stabilizer into the oligomeric composition at the radiation-curing stage was shown. The introduction of benzon OA as a stabilizer is shown to reduce the rate of photodegradation.
