| Abstract | ||
| The present work deals with the preparation and thermal investigation of interpenetrating networks (IPNs) of epoxy resin and N -phenyl maleamic acid The following monobasic amic acids were synthesized : PMA, After characterization by IR spectroscop,the IPNs were studied thermally using TGA and IGA techniques. For TGA measurements the following points were observed: The comparison of (Wt %)350 with IDT and CDT values reveal its agreement with CDT more than IDT values. this observation indicate that IDT values are not suitable measure for thermal stability.The values of IDT,CDT and (Wt%)350 are nearly almost the same in the range(25,50,80,120,180) C This behavior may be due to the inclusion of second polymer in the epoxy matrix The higher (Wt%)350 value was observed in natural medium.As well The activation energy of activation (by using Fuoss equation) was also estimated . | ||
