Title (EN) PROCESS FOR THE HYDROGENATION OF A POLYMER COMPOSED OF DIENE MONOMER UNITS AND A NITRILE GROUP-CONTAINING MONOMER UNITS
(FR) PROCEDE RELATIF A L'HYDROGENATION D'UN POLYMERE COMPOSE DE MOTIFS MONOMERES DIENIQUES ET D'UNITES MONOMERES A GROUPE NITRILE
Abstract:
(EN) Process for the hydrogenation of a polymer composed of conjugated diene monomer units and a nitrile group-containing monomer units, in which hydrogenation is carried out in the presence of hydrazine, and an oxidizing compound, with the hydrogenation being carried out in the presence of a antioxidant. It is preferred for NBR to be used as polymer.
(FR) L'invention concerne un procédé relatif a l'hydrogénation d'un polymère composé de motifs monomères diéniques conjugués et d'unités monomères à groupe nitrile. L'hydrogénation est conduite en présence d'hydrazine, d'un composé oxydant et d'un antioxydant. Le polymère utilisé de préférence est du caoutchouc de nitrile-butadiène.
