1517662 Supported catalysts comprising polymer complexed transition metals CALIFORNIA INSTITUTE OF TECHNOLOGY 13 July 1976 [12 March 1976] 29156/76 Heading B1E [Also in Divisions C2 and C3] Catalysts for hydroformylation, hydrogenation, hydrosilysation, acetoxylation or polymerisation comprise polymers containing at least 0.1% by wt. of amine-coordinated Group IV, VI, VII or VIII transition metal prepared by U.V. irradiation of a reaction medium containing a compound of said metal in which the metal is in a valency state below its maximum and a polymer containing amine groups. The polymer may be in the form of a coating on glass beads. Examples describe a catalyst prepared from polyvinyl-pyrrolidone and CO 2 (CO) 8 and its use in hydroformylation of pentene.
