Abstract
Thermally stimulated depolarization current spectra in poly-blends of polyvinylchloride(PVC)/polyacrylonitrile-butadiene (NBR) films have be en investigated. With the aid of a thermal sampling technique, the com plex spectra could be resolved into their elementary processes. PVC an d NBR were found to be miscible as evidenced by the existence of the c ompensation law. The dependence of the compensation temperature on the nitrile content confirms that dipole-dipole interaction was the most likely in this system. Hence, we are led to conclude that PVC and NBR are thermodynamically miscible.
