Abstract
In the hydrogenation of polymers or copolymers synthesized from dienes, or containing diene hydrocarbons, which is as a rule carried out in an organic solvent using hydrogen in the presence of conventional complex hydrogenation catalysts based on metals of sub-group 8 of the periodic table of the elements and aluminum trialkyls it is important to have from 0.5 to 50 moles of water present in the hydrogenation zone per mole of the heavy metal component of the catalyst. The hydrogenation time can be substantially reduced by this measure.
