Description 1083-1087
Thermal behavior of symmetric double schiff’s bases containing cardo group has been studied by TGA and DSC techniques
at 10°C/min in nitrogen atmosphere. DSC transitions, thermal stability and kinetic parameters are affected by nature and
position of substituents. Schiff’s bases are thermally stable between 173-272°C and followed either a single step or two steps
degradation (fractional or integral order). Different magnitudes of n, E and A suggested different degradation mechanisms. A
large and negative magnitudes of “S* confirmed highly ordered transition state, while positive magnitudes of “S* confirmed less
ordered transition state.
