摘要：
The thermal transformations proceeding in gamma-irradiated polyacrylonitrile were studied. it was found that irradiation results in decrease in the molecular mass of the polymer and transformation of a fraction of the nitrile groups into acid groups. The decrease in molecular mass affects the kinetics of the thermal reactions occurring in the; polymer, whereas the appearance of the acidic groups in the course of irradiation does not affect the behavior of the polymer at high temperatures. This is due to the specific distribution of the radiation-induced acidic groups, which are clustered in the polymer.
