Abstract
The changes in the electrophysical and paramagnetic characteristics of PAN fibres during their heat treatment are similar to the corresponding changes in heat treatment of other polymer [10]; the character of these changes allows tracking the appearance and development of a polyconjugated structure in heat treatment of PAN fibres with the characteristic mobility of the π-electrons and ability to form paramagnetic centers.
