Thermochimica Acta, 1994
Abstract DSC of melanin displays well-defined phase transitions as compared to TG. The homopolymer melanin-a katatype aromatics is thermally stable up to about 31 °C, and loses a unit of indole-5,6-quinone with a release of heat of 120.2 J g −1 .

Thermal stability of polyaniline
Synthetic Metals, 1988Abstract The thermal stability of conductive polyaniline prepared by the chemical oxidation of aniline with ammonium persulfate in hydrochloric acid was investigated by a heat-aging test at 150 °C. The stability in terms of electrical conductivity was found to depend upon the sample form as well as on the environment.

Thermal stability of elastomers
Journal of Thermal Analysis, 1984Thermal transitions of elastomers are classified and problems concerning their stability are discussed. It is concluded that in the case of general-purpose elastomers no simple correlation exists between the energy of the bonds in the skeleton of a chain and their thermal stability.

Thermal stability of fullerenes
Technical Physics Letters, 2004We have studied the thermal stability of fullerenes, for which there are discrepancies in available literature. A critical temperature of the thermal stability of C60 and C70 molecules was determined by thermodynamic calculations as a function of the pressure and the ratio of carbon to a buffer gas (helium or argon).

Thermal stability of polyaniline
Synthetic Metals, 1989Abstract Thermal stability data for neutral (emeraldine base) and doped polyaniline with various counter anions are reported. The emeraldine base is a highly heat-stable polymer, with thermal stability up to 420 °C. The thermal stability of doped polyaniline is dependent on the counter anion.

Thermal Stability of Polysulphone
Die Makromolekulare Chemie, 1969AbstractPolysulphone, prepared from 2.2‐bis(4‐hydroxyphenyl)propane and 4.4′‐dichlorodiphenyl sulphone, degrades when heated at 380°C i. vac. The mol. wt. increases with time of heating until after about 3 hrs gelation occurs. In addition to crosslinking scission processes have been shown to be important.
