Book excerpt: Epoxidation of natural rubber was carried out by using hydrogen peroxide and acetic acid on natural rubber latex at pH5 and temperature below 15 C. Thermorgravimetric analysis, bomb calorimetric measurements, proton and 13C NMR spectra of varoius epoxidised natural rubber samples were studied. The thermal stability of the exposided natural rubber is found to be superior than natural rubber. It is found that the NMR methods are better and simpler than the HBr-acetic acidtitration in the determination of the extent of epoxidation of natural rubber. [Authors' abstract].
