Oxidation resistance and thermal stability of natural rubber (NR) can be improved by diimide transfer hydrogenation in the latex phase. In this research, non-catalytic diimide transfer hydrogenation of concentrated NR latex was accomplished at various proportions of hydrazine hydrate/hydrogen peroxide. The system was stabilized with the addition of sodium hydroxide. Hydrogenated natural rubber (HNR) was characterized by Fourier Transform Infra Red analysis and degree of hydrogenation. The possibility of side reactions during hydrogenation was also ...

Rubber plasticizer is used to improve rubber processability so as to shorten time and reduce energy consumption
during compounding. In general, rubber plasticizer is nonrenewable and environmentally harmful petroleum
derivatives due to the carcinogenic property. Environmentally friendly plasticizer can be produced by transfer
hydrogenation of vegetable oil. The research was aimed to synthesize new rubber plasticizer from transfer hydrogenation
of castor oil using diimide compound which was generated in situ by oxidation of hydrazine hydrate
and hydrogen peroxide as well ...
