Notes:
Hyperelectronic polarization is a molecular mechanism which can produce very large dielectric constants in certain macromolecular solids. The present paper reports studies of the frequency, pressure, and temperature responses of this extreme polarization and related electronic conductivity on a variety of new polymers. The polymers studied were quinazone, metallo-organic dithiooxamide type, and pyropolymers. The latter were examined in pure and in metal-doped forms. Dielectric constants ranging from 10 to 500 were observed for the quinazone polymer, which was, incidentally, found to exist in two forms. Dielectric constants ranged from 30 to 100 for the metallo-organic polymer from 25 to 10,000 for the pure pyropolymer and were of the order of 500 for a calcium doped pyropolymer. One set of nickel-doped pyropolymers was found to conduct quite well (resistivity 76.8 × 10-6 ohm-cm).
