Abstract: This paper studies the catalytic hydrogenation of C=C in poly(butadiene-coacrylonitrile) copolymers containing different amount of butadiene by using RHCl·[P(C6H5)3]3as the catalyst.The results of IR and NMR demonstrate that RhCl[P(C6H5)3]3is an efficient catalyst and shows an excellent selectivity.The catalyst provides quantitative hydrogenation of C=C unsaturation without any hydrogenation of CN.It is necessary to keep enough reaction time so that the double bonds can be hydrogenated completely.

Key words: Butadiene-co-acrylonitrile copolymer, RhCl[P(C6H5)3]3Homogeneous catalysis, Selective hydrogenation
