Abstract
The present invention provides a novel process for selectively hydrogenating the carbon-carbon double bonds in diene-based polymers which are present in latex form, this means as a suspension of diene-based polymer particles in an aqueous medium, using a Ruthenium or Osmium-based complex catalyst without any organic solvent.
