  • Patent number: 4876314
    Abstract: A process for selectively hydrogenating a polymer containing ethylenic unsaturation and cyano groups with a catalyst prepared by combining one or more of certain palladium compounds and one or more of alkylalumoxanes in a suitable solvent or diluent. The hydrogenation is accomplished in a suitable solvent for the polymer at a temperature within the range from about 20.degree. C. to about 175.degree. C. at a total pressure within the range from about 50 to about 1,000 psig and at a hydrogen partial pressure within the range from about 50 to about 950 psig. The hydrogenation can be accomplished so as to convert at least about 85% of the ethylenic unsaturation contained initially in the polymer without converting a significant portion (less than about 5%) of the cyano groups to amine groups.
