摘要：
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.
