Article Description

Poly(propylene imine) dendrimer (G2-PPI) terminated by nitrogen-containing triolefinic macrocycle on the periphery (G2-M) was synthesized by a nucleophilic substitution reaction. The structure and composition of G2-M were characterized by FT-IR, H-NMR and elemental analysis. The Rh dendrimer-stabilized catalyst (G2-M(Rh)) was prepared by utilizing G2-M as stabilizer and analyzed by UV–Vis spectroscopy, H-NMR spectrometry, XPS and XRD. G2-M(Rh) demonstrates excellent catalytic activity and selectivity for the hydrogenation of nitrile-butadiene rubber (NBR) and styrene-butadiene rubber (SBR), and Rh residue contents for HNBR and HSBR are only 35 and 13 ppm, respectively, without any post treatment.
