  • Patent number: 8314188
    Abstract: Proposed is a process for the continuous hydrogenation of carbon-carbon double bonds in an unsaturated polymer to produce a hydrogenated polymer, said unsaturated polymer being based on a conjugated diolefin and at least one other copolymerizable monomer, in the presence of a homogeneous or heterogeneous catalyst, wherein said unsaturated polymer, hydrogen and said homogeneous or heterogeneous catalyst is passed through a multistage agitated reactor, comprising a cylindrical, elongated shell having closed ends and separated by baffles into a multiplicity of discrete chambers with access from one chamber to another through concentric circular openings, axially centered with said baffles and a continuous rotatable shaft extending concentric with said baffles within said shell with at least one impeller attached thereto positioned in each chamber, said continuous rotatable shaft and said circular openings providing annular openings and said hydrogenated polymer being withdrawn at the opposite end of the multista
