To study the thermal stability of nitroplasticizer (NP), vinyl copolymer elastomer (VCE), and VCE composites, we conduct systematic TGA characterizations in non-isothermal and isothermal modes. We investigate the effects of NP concentration, filler concentration, and time on the aging behaviors of VCE polymer in its composites. We probe the structural changes in the VCE samples before and after thermal treatments with FTIR characterization. The results suggest that the thermal stability of NP decreases as the filler concentration and temperature increase. The deteriorated NP greatly degrades the stability of the VCE polymer. Through the isothermal TGA study, we also estimate the NP transport properties to migrate through the VCE/filler composites.LA-UR-14-21494
