1. A process for selectively hydrogenating carbon-carbon double bonds in a diene-based polymer, the process comprising selectively hydrogenating carbon-carbon double bonds of a diene-based polymer in the presence of a group VIIIb metal containing catalyst supported on a carrier material comprising at least one hyper-branched polymer, at a temperature of 20° C. to 60° C. and in a solvent selected from the group consisting of ketones, ethers and aromatic hydrocarbons.
