Property of Hydrogenated Nitrile Rubber Catalyzed by a Novel Rh-Ru Bimetallic System
Rh-Ru bimetallic complex is a novel catalyst used to hydrogenate nitrile rubber, which has high activity and high selectivity. Hydrogenated nitrile rubber with a degree of hydrogenation over 99% and gel-free was obtained using this homogeneous catalyst. In this paper, relative molecular weight and mechanical properties of three types of HNBR, including HNBR hydrogenated by Rh-Ru bimetallic catalyst, Therban A3406 and Zetpol 2000L, were analyzed and compared. The results showed that the relative molecular weight of HNBR increased a little after hydrogenation compared to NBR, its mechanical properties were superior to those of Therban A3406 and Zetpol 2000L, and their oil resistant and rheological curves at 130°C and 140°C in the range of shear rate 0∼100s-1 were similar.
