1784.  JONES, J. P., AND AXE, W. N. (Phillips Petroleum Co.). Reaction of Diolefin Polymers With Hydrogen and Carbon Monoxide. United States Patent 2,544,555, Mar. 6, 1951. Chem. Abs., vol. 45, 1951, p. 4967.

Reaction of polymeric hydrocarbons (I), having a greater degree of unsaturation than a monoolefin and a molecular weight of 200-800, with H2 and CO in the presence of a suitable Fischer-Tropsch catalyst forms a resinous solid O-containing material (II). The reaction is preferably conducted in 2 steps, the formation of a resinous product (III) and the further reaction of (III) with H2 in the absence of CO either in the presence of the original or a substitute hydrogenating catalyst. The preferred Fischer-Tropsch catalyst is a Co-thoria-kieselguhr mixture (IV) with the respective weight ratio of 100 : 18: 100. Thus, to a cyclohexane solution of (I), or "claytower polymers", 2:1, containing 5% of (IV), an equimolar mixture of H and CO is added at 500 p.s.i. The mixture is agitated and kept at 300º F. for 30 min. before the gases are released. The system is purged of CO, and then H2 is added at 500 p.s.i. and the mixture maintained at 300º F. for 30 min. After cooling the chief reaction product is a (II) having properties suitable for use in paints and lacquers.
