Thermal decomposition was carried out on 10 mg
samples in an aluminium holder either under
nitrogen or air flow (60 cm 3 min -]) by
thermogravimetry (TG) at heating rates in the
range 1.25-40°C min -1 and differential scanning
calorimetry (DSC) at 10°C min -1 using a Du Pont
2100 thermal analyser provided with a TGA 2950
module.
