Abstract
The results of heat treatment influence on chemical polyvinylidenfluoride carbonification products are given with the help of electron paramagnetic resonance spectroscopy method. For the first time step-like increase of paramagnetic centers concentration has been observed at heat treatment at over 250 °С which is accompanied by the changes in parameters of electron paramagnetic resonance signals. At conservation of synthesized samples there is partial decrease of magnetic activity within three months.
