Natural rubber (NR) tapped from three clones of the rubber tree [Heveabrasiliensis (Willd. ex Adr. de Juss. Muell.-Arg.)] over a seven month period was obtained by coagulation of lattices with 10% acid acetic and dried at 65 degrees C. TG-DTG curves were used to monitor thermal properties of NR. The TG-DTG results indicated very small differences among the clones and tappings, except in the value of T-f-T-0, which indicated that the IAC 301 clone suffered the fastest thermal degradation, during decomposition of the dried, raw NR. There was no significant difference in T-g values among clones and tappings.
