The thermal properties of doped Azopolyester were obtained by solution casting technique. Many theories have been suggested by various thermal stability mechanisms in organic solids. Since the polymers of the present study behave like semiconductors, these theories may be extended to explain thermal stability. In this section, the thermal stability theories proposed by O'Dwyer, TGA analysis, and measurements were discussed. The thermal stability properties reveal that the conductivity is appreciable in the temperature ranging from 30°C to 70°C (303 to 343K) and when it is more than 70°C (343 K) the conductivity is drastically reduced and polymeric blends undergo a gradual weight loss in the temperature ranging from 400-800°C due to attributed loss of volatile solvents trapped in the polymer. These studies are done with the help of O'Dwyer basic theory of thermal stability.

Abstract


The thermal properties of doped Azopolyester were obtained by solution casting technique. Many theories have been suggested by various thermal stability mechanisms in organic solids. Since the polymers of the present study behave like semiconductors, these theories may be extended to explain thermal stability. In this section, the thermal stability theories proposed by O'Dwyer, TGA analysis, and measurements were discussed. The thermal stability properties reveal that the conductivity is appreciable in the temperature ranging from 30°C to 70°C (303 to 343K) and when it is more than 70°C (343 K) the conductivity is drastically reduced and polymeric blends undergo a gradual weight loss in the temperature ranging from 400-800°C due to attributed loss of volatile solvents trapped in the polymer. These studies are done with the help of O'Dwyer basic theory of thermal stability.
