<p>SELECTIVE HYDROGENATION OF UNSATURATED HYDROCARBON POLYMERS Selective hydrogenation of unsaturated hydrocarbon polymers is achieved utilizing compounds of rhodium, ruthenium and iridium in the presence of hydrogen. The hydrogenation is laryelyselective with respect to external or pendant points of unsaturation on the polymer chain. The invention is particularly pertinent with respect to polymers made from dienes such as butadiene, isoprene, styrene-butadiene and the like which are utilized in the manufacture of rubber compounds.</p> |
