<p>A process for the hydrogenation of C=C bonds in a polymer comprising a conjugated diolefin and at least one other comonomer comprises hydrogenating a soln. of the polymer at 100-180 [deg]C and at a H2 pressure of 0.7-15.5 MPa in the presence of a catalyst of formula (I). OsQX(CO)(L)(PR3)2 (I), Q = H or phenylvinyl; X = halogen, tetrahydroborate and alkyl- or aryl-carboxylate; L = O2, benzonitrile or no ligand; and R = cyclohexyl, isopropyl, secondary butyl and tertiary butyl, the tertiary butyl being present only when one R is methyl; provided that when Q is phenylvinyl, X is halogen and L is no ligand, and when X is alkyl- or aryl-carboxylate, Q is H and L is no ligand, the halogen being selected from Cl and Br.</p> |
