Degradation kinetics of sequential IPNs, based on novolac resin and poly (2-ethyl hexyl acrylate), are studied at linear heating rates of 2A degrees C/min, 5A degrees C/min, 10A degrees C/min and 20A degrees C/min by thermogravimetric analyser (TGA). Activation energy (E (a) and order (n) of thermal decomposition reaction for IPNs and pure phenolic resin are evaluated from TGA curves using differential method of Freeman and Carroll. Decrease in T (g) with an increase of acrylate content in IPNs are seen. Lower activation energy (E (a')), as calculated by applying Kissinger equation, for the concerned transition of IPNs, compared to that of pure phenolic resin is quite evident from DSC study.
