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°C. The effects of reaction temperature, reaction time, solvent, and MSH / LNR weight ratio on the percentage of hydrogenation were evaluated. 1 H NMR analysis revealed that ~80% hydrogenation was achieved with a weight ratio of MSH : LNR = 1:1 at 100°C in o ‐xylene within 60 min.
