Thermal degradation behavior of 2-ATPHMDAF-I terpolymer.

Terpolymer	Stages of decomposition	Temp. range; (°C)	Species degraded	Wt. loss (%)
				Expt.	Calc.
2-ATPHMDAF-I	First	40–130	One water molecule	6.12	6.36
	Second	130–230	One –SH and one –NH2 group	23.52	23.67
	Third	230–320	Benzene ring along with side chain of hexamethylenediamine moiety	59.66	59.71
	Forth	320–990	Complete loss of hexamethylenediamine moiety	98.67	100
