Thermal Transformations of Polyoxadiazoles

Resumo

Changes of the structural characteristics and electrical properties of fibers based on polyoxadiazole (Arselon) upon a low-temperature thermal treatment in an inert atmosphere were studied. Extremal dependences of the conductivity of the fibers on treatment temperature were observed and a mechanism of this process was suggested. The X-ray diffraction parameters of the Arselon fibers were determined for the extreme states and practical recommendations were made for using a preliminary heating of the fibers.
