The present invention provides a novel process for subjecting a diene-based-polymer to a metathesis reaction in a first step and a selective hydrogenation of the carbon-carbon double bonds present in such diene-based polymers in a second step using a ruthenium or osmium based complex catalyst, wherein the diene-based polymer is present in latex form, this means as a suspension of diene-based polymer particles in an aqueous medium.

Tandem metathesis and hydrogenation of diene-based polymers in latex

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.

Hydrogenation of a diene-based polymer latex

The present invention relates to a process for the hydrogenation of the carbon-carbon double bonds in diene-based polymers in bulk form by treatment of said diene-based polymer with hydrogen in the presence of an iridium containing catalyst and in the absence of any organic solvent.

Hydrogenation of diene-based polymers

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.
