- Abstract
Thermal oxidation kinetics of raw constant viscosity natural rubber (CVNR) prepared with fresh natural rubber (NR) latex containing several difference viscosity stabilizers was studied. The comparison with the ageing characteristics of hot oxygen (hot air), ozone and light oxygen (ultraviolet light) of vulcanizate of raw CVNR was also studied. The results show that the thermal oxidation activation energies of CVNR prepared with hydroxylamine hydrochloride, hydrazine hydrate, aniline or semicarbazide hydrochloride are higher, extraordinarily that of aniline. The thermal oxidation activation energy of CVNR prepared with hydroxylammonium sulphate was lower and also compared to that of the control. The oxidation kinetics of raw CVNR had good correlation with thermal oxidation ageing characteristics of vulcanizate of raw CVNR, and had no correlation with the ageing characteristics of ozone and light oxygen.
