Abstract
Abstract The present work deals with the preparation and thermal investigation of interpenetrating networks (IPNs) of epoxy resin and N-2 phenyl maleamic acid the following monobasic amic acids was synthesized (2FMA), For this study. After characterization by IR spectroscopy, the IPNs were studied thermally using Thermo Gravimetric Analysis )TGA (and Isothermal Gravimetric Analysis )IGA (techniques. For TGA measurements the following points were observed: The comparison of weight percentages at 200 Cº (Wt%)200 with Initial Decomposition Temperature )IDT) and Complete Decomposition Temperature) CDT( values reveal its agreement with CDT more than Complete Decomposition Temperature values )IDT(. this observation indicate that Initial Decomposition Temperature values )IDT( are not suitable measure for thermal stability. The values of Initial Decomposition Temperature )IDT) and Complete Decomposition Temperature )CDT( and weight percentages at 200 Cº (Wt%)200 are nearly almost the same in the range (25,50,80,120,180) Cº This behavior may be due to the inclusion of second polymer in the epoxy matrix The higher weight percentages at 200 Cº (Wt%)200 value was observed in neutral medium. As well The activation energy of activation (by using Fuoss equation) was also estimated.
