CA 2482355

The invention concerns a method for hydrogenation of unsaturated polymers in dispersed medium based on an oxidation-reduction system containing hydrazine, an oxidant such as a peroxide and optionally a carboxylic acid. The hydrogenation rate can reach 100 % in certain conditions.

L'invention décrit un procédé d'hydrogénation de polymères insaturés en milieu dispersé basé sur un système oxydo-réducteur contenant de l'hydrazine, un oxydant tel que un peroxyde et éventuellement un acide carboxylique. Le taux d'hydrogénation peut atteindre sous certaines conditions 100%.
