ABSTRACT:
The present invention relates to a process for the selective hydrogenation of the carbon-carbon double bonds in diene-based polymers in bulk form by treatment of the polymer with hydrogen in the presence of a platinum group metal containing catalyst and in the absence of any organic solvent.
