The synthetic route used was that of ring-opening polymerization catalyzed by sodium hydride and subsequent crosslinking using DCP. The reaction occurred at emperature above 200°C in argon atmosphere. The pyrolysis was performed at temperature of 1000°C for 1 hour. The samples were submitted to FTIR and 13C, 29Si and 1H solid/solution NMR analyzes to elucidate the structures before and after the pyrolysis. The PA12-HTT1800 hybrid polymer was formed and after pyrolysis of the material, showed a single-phase and amorphous structure according to the TEM and XRD analysis. The Raman spectroscopy was used to confirm the presence of free carbon in the structure.
