Conclusions
These polymers may be used to produce thermal resistors. Thermal resistors based on polymers produced by condensation polymerization of paraphenylenediamine with tetrabromethane at 150 and 250 °C (whose I–V characteristics have a descending region) may be used in various types of automatic apparatus, control apparatus, protective apparatus, etc.
Thermal resistors based on polymers produced by condensation polymerization of paraphenylenediamine with hexachlorethane at 150 and 350 ° C (whose nominal resistances decrease by four orders of magnitude as the temperature is increased from 20 to 300 ° C) can be used as temperature-sensitive pickups for temperature measurement and stabilization.
