Dielectric losses in polyacrylonitrile (PAN) and three pyrolyzates were studied between 1 Ha. and 300 kHz. Pure PAN has at 20Β°C. a very broad low region with a maximum at 70 HI. which is ascribed to CN groups. Powdered PAN was pyrolyzed in a nitrogen atmosphere at 170, 220, and 300OC. PAN-170 has th
