of ochres used in bark paintings. Thermogravimetricanalysis (TG) combined with differential scanning calorimetry (DSC) and mass spectrometry (MS) has been used to examine paint obtained from an indigenous bark painting provided by the Australian
The thermal degradation of a fully cured polycyanurate thermosetting material was examined by monitoring the mass loss at
various temperatures ranging from 200 to 220‡C. The effect of the copper naphthenate catalyst, generally used to facilitate
curing, is also studied. A decrease in weight is observed with increasing time at elevated temperatures in the systems containing
copper naphthenate, with the onset of degradation occurring sooner with higher concentrations of the copper compound. The
apparent activation energy for degradation is 220±30 kJ mol−1.

In this work the thermal properties of chitins of different origin were compared using a thermogravimetric technique. The
αs-αr method, which makes possible a comparison of the thermal resistances of materials with similar thermostability, was used.
The basic range of thermal conversion was determined. In this range, the thermal resistance depends on the chitin origin.
The value of activation energy was calculated. No influence on the average molecular mass, crystallinity and the degree of
acetylation on the thermal resistance was observed. On the other hand, it was found that the thermal stability depends on
the size and perfection of crystallites as well as on the crystalline form of the chitin.

Thermal degradation kinetics of copolymers based on bis-phenol A ethoxylated dimethacrylate (Bis-EMA) with triethylene glycol
dimethacrylate (TEGDMA), and urethane dimethacrylate (UDMA) with TEGDMA in wt/wt ratios 30/70, 50/50, or 70/30 were investigated
using thermogravimetric analysis as a means to provide specific information regarding the internal structures of these resins.
Thermogravimetric scans were taken at four different heating rates to perform an isoconversional analysis to determine the
change of the effective activation energy as a function of conversion. A two-step degradation mechanism was found to occur
in almost all copolymer compositions attributed to the existence of inhomogeneities in the macromolecular structure and the
formation of weak links inside the polymeric network.
