Also, the first derivative of each curve was plotted to obtain the DTGA curves.
The TGA and DTGA curves of the compounds are compared in figures 2 and 3, with the decomposition up to 400[degrees]C, the peak decomposition temperatures and the corresponding peak decomposition rates of the compounds are tabulated in table 2.
This was read as the peak temperature in the DTGA traces and char yield representing the final residue at T - 600[degrees]C.
Only one DTGA peak is observed, showing that thermal degradation temperature of PS has increased from 423 to 434, 453, 456, and 460[degrees]C with 8.
Thermal decomposition of these polymers involves two overlapping steps, which are difficult to distinguish from TGA curves, but more obvious from DTGA curves.
