In this study, the thermal stability and maximum degradation temperature of pure epoxy resin and the effect of 0.5, 1 and 1.5% elastomeric nanoparticles on epoxy resin by thermal gravimetric analysis at different heating rates of 10, 15 and 20 oc/min have been investigated. Evaluation of thermal degradation behavior of epoxy resins and nanocomposites showed that thermal degradation is single-stage. 0.5% nanocomposite increases thermal stability by increasing the heating rate and also reduces the rate of thermal degradation. with increasing heating rate, T50 for epoxy resin and 1% nanocomposite increased, and also for 0.5 and 1.5% nanocomposites initially increased, and then decreased . By adding elastomeric nanoparticles to the epoxy resin matrix, the amount of Tm nanocomposites increased.
