• Liquid natural rubber
• Non-catalytic hydrogenation

This article reports an efficient, mild-temperature method for the hydrogenation of liquid natural rubber (LNR). The hydrogenation of LNR was studied using diimide generated in situ from the thermolysis of 2,4,6-trimethylbenzenesulfonyl hydrazide (MSH) in o-xylene at 100 degrees C. The effects of reaction temperature, reaction time, solvent, and MSH/LNR weight ratio on the percentage of hydrogenation were evaluated. H-1 NMR analysis revealed that similar to 80% hydrogenation was achieved with a weight ratio of MSH: LNR = 1:1 at 100 degrees C in o-xylene within 60 min.
