Latex collected from natural rubber trees forming membranes can be used as biomaterials in several fields being the temperature
a key parameter. Thermogravimetry (TG) coupled to Fourier transform infrared spectroscopy (FTIR) is a useful technique to
investigate the thermal degradation of both latex and cast films (membranes), wich were obtained from Hevea brasiliensis (RRIM 600 clone) and used without stabilization. The membranes were prepared by casting the latex onto a glass substrate
at 65°C for 6 h. The thermal degradation was followed by FTIR spectra acquisition along the process, allowing the identification
of the gaseous components evolved upon the thermal treatment. According to TG measurements, the main processes of thermal
degradation of the latex and membranes occur at three temperature intervals for both.
