The thermal oxidative behaviour of natural rubber cured with four different peroxides namely 2,5-dimethyl-2,5-bis(tert-butylperoxy) hexane (DHBP), 1,1'-di(tert-butylperoxy)-3,3,5-trimethylcyclohexane (TMCH), 1,3 1,4-bis (tert-butyl peroxy isopropyl) benzene (DIPP) and dicumyl peroxide (DCP) was studied. Fourier transform infrared spectroscopy (FTIR) and Thermo gravimetric analysis (TGA) were used to characterize the byproducts formed. Mechanical properties of the vulcanizates cured with different peroxides were measured. Among the four peroxides, DHBP and DIPP registered the best mechanical properties, however unlike DCP, DHBP imparted smell free vulcanizates. Out of the four different peroxides used DIPP showed the best overall balance of properties and thermal stability.
