摘要：
Heat treated metal-containing polyacrylonitriles that were obtained in air (220-degrees, 13 h) and based on chrome-, molybdenum-, and tungstencarbonyl polyacrylonitriles, were investigated using the ESR method. As a result of heat treatment, oxides of corresponding metals and paramagnetic centers appeared, whose concentration was dependent on the duration of heating. Subsequent carbonization (980-degrees, argon) led to the reduction of metal oxides and to the disappearance of paramagnetic centers.
